Objective: To separate management traffic from data/customer traffic in your Cisco XR routers. Preferably, Data and Management are into 2 separate network domains. Pre-requisite: UTP cables (for each RSP management port in case for switchover) are connected to a network switch to access the OOB management gateway * * Management IP Configuration* *  1. Configure the vrf for management vrf management  description VRF for Out-of-Band  address-family ipv4 unicast 2. Set the physical IP address on each RSP management port. There are total of…

As per Cisco official site definition of FPD: An FPD refers to any programmable hardware device on a router, which includes a Field Programmable Gate Array (FPGA) and Read Only Memory Monitor (ROMMON). Cisco IOS® XR routers use a number of FPDs that are crucial for the function of route processors, line cards, shared port adapters (SPAs), SPA Interface Processors (SIPs), and fan trays. Sample of upgrading fpd in ASR9000 running in IOS-XR. Linecard used is 24x10GE Tomahawk linecard. A.…

Static Route Configuration Examples in Cisco (IOS-XR)  for BGP aggregated prefix advertisements In order to advertise the aggregated routes (and default routes) via BGP, it should exists in the routing table, that’s the #1 rule. If these summarized routes (/16) are not existing and only smaller subnets are learned via the IGP(e.g. OSPF,IS-IS), then configure static route and next hop e.g. Null0. Configuration: router static address-family ipv4 unicast 0.0.0.0/0 Null0 172.16.0.0/16 Null0 ! address-family ipv6 unicast ::/0 Null0 fd41:c8be:2153:f400::/64 Null0…

Originating BGP advertisement can be configured to any iBGP peer router. Here’s the sample configuration of originating BGP routes and community tagging in Cisco Assuming these are the summarized prefixes that you want to advertise via BGP. 111.111.0.0/16 222.222.0.0/16 Configuration: prefix-set SITE1 111.111.0.0/16, 222.222.0.0/16 end-set route-policy bgp-statement if destination in SITE1 then set community (12345:111) endif end-policy router bgp 11111 nsr bgp router-id 1.1.1.1 bgp graceful-restart address-family ipv4 unicast network 111.111.0.0/16 network 222.222.0.0/16 neighbor-group RR-IBG remote-as 11111 password encrypted 2185073C7B74154C…
