BGP Prefix Limit Configuration in Cisco, Juniper and Nokia - Interop

BGP Prefix Limit

Maximum Prefix-limit is used to control the BGP peer not to overload your BGP routing table and it helps to avoid the situation. let's explore how to configure in Cisco, Juniper, and Nokia router


Cisco Configuration

 !
router bgp 300
 neighbor 192.168.1.1
  address-family ipv4 unicast
   maximum-prefix <max-limit> <percentage> <Actions>
  !
 !

Juniper  Configuration

edit protocol
bgp {
        group nokia {
            neighbor 192.168.0.1 {
                family inet {
                    unicast {
                        prefix-limit {
                            maximum 1000;
                            teardown;
                        }
                    }


Nokia Configuration

/configure router bgp
            group "juniper"
                type external
                local-as 100
                neighbor 192.168.0.2
                    prefix-limit <family> <prefix-limit>
                    peer-as 200
                exit

Configuration of the epipe/l2circuit on the Nokia 7750 SR/7250 IXR

Epipe Configuration on Nokia 7750 SR This article explains how to configure epipe between Nokia SR routers. The Cisco term is referred to as xconnect and the juniper term is L2circuit. Basic Theories: Epipe name itself identifies it's a point-to-point connection that uses Ethernet encapsulation to pass data bits/bytes between two endpoints. Service provider core act as a layer 2 switch for customer traffic. In other words, this helps to extend the IP segment of the same subnet shared between 2 different locations. Topology: ISIS Level 2 and LDP are preconfigured. let's explore the setup to configure epipe and initiate traffic between the 2 sites. LDP is used to signal the Service label between end nodes participating in epipe. Nokia: SAP-MTU and Service MTU play an important role. To bring up the epipe between 2 end nodes we need to take care of Service-MTU and Sap port MTU. SAP-port MTU and Service MTU should be the same if the encapsulation is null. If the encapsulation is do...

How to configure SFM/ Card/MDA in Nokia SR 7750/77XX series routers

Image
We going to discuss how to configure and bring up the Nokia chassis for the first-time installation like SFM, IOM/IMM Card, and MDA on Nokia 7750/77XX series router. SFM Card - Switch Fabric Module which is an internal backplane used to switch traffic between different slots on the router chassis. IMM -    Integrated Media Module which is your line card with a fixed number of media/ports IOM - Input/Output Module this type of card we can insert different types of media/ports based on the supported type by each Chassis. Let us explore how to identify and configure our Nokia SR series routers. 1. First find the SFM Type inserted on the Nokia Router. as per the output we need to configure  SFM5 to bring up the Switch fabric module A:SR1# configure sfm 1 sfm-type m-sfm5-12 Now SFM is configured let's find the Card Type using the "show card" command  *A:SR1# configure card 1 card-type "iom3-xp" Now, we are in the final phase to bring up the ports. check and configur...
