Jawahar Annadhurai
Very good place to learn, convinent ours that fits your work Schedule, Sanchit is one of awesome Instructure I am taking class with, we are not just taking online class just to sit and watch, we actually interact and share Ideas in the class
Omar Monads
One of my friends recommended about this to me and unfortunately I ignored him for few months. Later I agreed him joined their classes. Since then I was blaming myself for not joining before. They are excellent in technology classes. They have students worldwide . If you want to get your #CCIE_Digit this is the right place for sure. When it comes to RnS classes, Sancchit Puri, You are the best!!!

    BGP Attributes

     BGP support a wide variety of path attribute, BGP chooses a route to a network based on the attributes of its path.

    Four categories of attributes exist are as follows:-

    • Well-know mandatory
    • Well-known discretionary
    • Optional transitive
    • Optional non-transitive

    Well-known mandatory attribute must be recognized by all BGP routers, present in all BGP updates, and passed on to other BGP routers. AS path, origin, and next hop.

    Well-known discretionary must be recognized by all BGP routers and passed on to other BGP routers but need not be present in an update. Local preference

    Optional transitive might or might not be recognized by a BGP router but is passed on to other BGP routers.

    If not recognized, it is marked as partial. Aggregation, community.

    Optional non-transitive If the BGP process does not recognize the attribute then it can ignore the update and not advertise the path to its peer. Multi-exit discriminator (MED), originator ID

     AS_Path attribute- this particular path attribute lists the autonomous system numbers in the end-to-end path.BGP uses AS_Path as its primary loop-prevention tool.

     AS_Path attribute is a well-known mandatory attribute. its list of AS through which updates are coming. The shortest AS_PATH list is more desirable.

    Next_hop is a well-known, mandatory attribute next hop means IP address to reach next autonomous system because BGP is AS by AS routing protocol.

    Origin attribute

    origin informs all AS in internetwork how network got introduced into BGP.

     (i)  represent IGP

     (e) represent EBGP

     (?) represent incomplete

    Weight Attribute is a cisco's attribute. its tell how to exit the AS, path with the highest weight is more desirable. weight is partial attribute, by default weight 0 learn route 32,769 for locally injected routes. its local to the router not advertise to any BGP peers.

    Local Preference Attribute

    Local preference define how to data traffic should exit from an Autonomous system. path with highest preference value is more desirable by default is 100, and the range 0 through 232  local preference is well known, discretionary attribute it is advertise only to iBGP neighbor within an Autonomous system.

    Concepts
    • In CUCM v10, new attributes were introduced to DN which are Enterprise Alternate Number and +E164 Alternate Number.
      • Each DN can be represented with 3 numbers
      • For example, the DN can be 3459, Enterprise Alternate DN 3103459, +E164 Alternate DN +97145673459 or 045673459
      • By default Enterprise Alternate Number and +E164 Alternate Number aren't reachable locally within the cluster
        • This can be enabled by checking 'Add to Local Route Partition' under DN configuration
        • Assign the PT to phones CSS
      • You can assign Enterprise Alternate Number or +E164 Alternate Number as PSTN failover
        • PSTN failover will be used when the destination SIP trunk isn't reachable
        • This PSTN failover is applicable for called Enterprise Alternate Number, called +E164 Alternate Number or called Directory URI
        • CUCM will try to dial the PSTN failover number
        • Calling Phone AAR CSS will be used to reach the PSTN Failover
    • GDPR and ILS and two independent components
      • ILS network will be established between ILS enabled clusters to exchange route strings
      • GDPR will advertise GDPR data over ILS enabled network
      • GDPR data can be
        • Local Directory URIs
        • Local Enterprise Alternate Numbers
        • Local +E164 Alternate Numbers
        • Local Enterprise Alternate Patterns
        • Local +E164 Alternate Patterns
        • Imported Alternate Numbers, Alternate Patterns and URIs
        • Learned Numbers, Patterns and URIs
        • PSTN Failover
      • Actual Call Routing is based on SIP Patterns of Route Strings pointing to SIP Trunks
    • Instead of advertising large number of Alternate Numbers, you can create Alternate Pattern to be advertised
      • You can create Enterprise Alternate Pattern and +E164 Alternate Pattern
      • These patterns can't be used for local dialing
      • For Pattern PSTN failover, there are 3 options:
        • No PSTN Failover, i.e. if SIP trunk isn't reachable, call will fail
        • Use Pattern as PSTN Failover Number - This will use the same pattern as PSTN failover
        • Apply Strip Digits and Prepend Digits to Pattern and Use for PSTN Failover
    • You must assign learnt numbers/patterns to partitions
      • GDPR patterns can't be left in None partition
      • The default partitions created are
        • Global Learned E164 Numbers - This will be assigned to Learnt +E164 Alternate Numbers
        • Global Learned E164 Patterns - This will be assigned to Learnt +E164 Alternate Patterns
        • Global Learned Enterprise Numbers - This will be assigned to Learnt Enterprise Alternate Numbers
        • Global Learned Enterprise Patterns - This will be assigned to Learnt Enterprise Alternate Patterns
      • These partitions should be included in phones CSSes to be able to dial remote cluster numbers
      • In case of overlap between Alternate Number and Pattern, Longest match is applied
    • If you are using CUBE within ILS network, you need to enable Send ILS Learned Destination Route String
      • When enabled, CUCM can tag the route string in the SIP header x-cisco-dest-route-string
      • CUBE can use the voice-class route route-tag feature to route using route-tag
      Configuration  
    1. Activate Inter-cluster Lookup Service
    2. Navigate to Enterprise Parameters
      1. Configure unique cluster name for each ILS cluster
      2. Configure Cluster Fully Qualified Domain Name
      3. Configure Organization Top Level Domain
    3. Navigate to Advanced Features > ILS Configuration
      1.  Select Cluster Role
      2. Configure Route String
      3. Configure Synchronization Timer
      4. Enable Advertise Global Dial Plan Replication Data to Remote Clusters
      5. Configure ILS Authentication (TLS or Password)
    4. Navigate to Phone DN
      1. Under Enterprise Alternate Number
        1. Configure Number Mask - The Alternate Number will be generated based on DN and Mask
        2. Enable Advertise Globally via ILS
        3. Enable Add to Local Partition and select the partition - This can make the Alternate number reachable locally within the cluster
      2. Under +E164 Alternate Number
        1. Configure Number Mask - The Alternate Number will be generated based on DN and Mask
        2. Enable Advertise Globally via ILS
        3. Enable Add to Local Partition and select the partition - This can make the Alternate number reachable locally within the cluster
      3. Configure Directory URI (this is covered in separate section)
      4. Under PSTN Failover for Enterprise Alternate Number, +E.164 Alternate Number, and URI Dialing assign +E164 or Enterprise Alternate Number as PSTN failover
    5. Navigate to Call Routing > Global Dial Plan Replication > Advertised Pattern > Add New
      1. Configure Pattern
      2. Select Pattern Type (Enterprise Alternate or +E164 Alternate)
      3. Configure PSTN Failover Policy
    6. Navigate to Call Routing > Global Dial Plan Replication > Partitions for Learned Numbers and Patterns
      1. Select the Partition for each GDPR Data Type
      2. You can mark GDPR Data as Urgent Priority
    7. Navigate to Call Routing > Global Dial Plan Replication > Blocked Learned Patterns (this will define numbers/patterns not to be installed in database)
    8. You can view Learnt Numbers and Patterns from Call Routing > Global Dial Plan Replication tab
    9. If you ILS SIP Trunks are pointing to CUBE, configure SIP Profile with Send ILS Learned Destination Route String enabled
