Ok, now that BGP has been covered, lets talk about filtering routes received from our neighbor. Here I have created some additional Loopbacks on R2 that are being advertised to R1: RP/0/7/CPU0:R1#sh ip route bgp Fri Mar 30 13:13:36.797 UTC B 200.100.200.100/32 [20/0] via 2.2.2.2, 00:00:42 B 200.200.200.200/32 [20/0] via 2.2.2.2, 13:45:00 B …
BGP, this is where it starts to get different with IOS XR. First up, configuring an iBGP peering with R2’s 150.1.12.2 in AS1 and advertise our loopback interface. RP/0/7/CPU0:R1(config)# RP/0/7/CPU0:R1(config)#router bgp 1 Let’s define the network we want to advertise, under the address family: RP/0/7/CPU0:R1(config-bgp)#address-family ipv4 unicast RP/0/7/CPU0:R1(config-bgp-af)#net 1.1.1.1/32 RP/0/7/CPU0:R1(config-bgp-af)#exit Now, we can configure the…
Time for some IS-IS routing! Between IS-IS and OSPF, those are the two most coming SP core routing protocols. RP/0/7/CPU0:R1#conf t Thu Mar 29 22:09:12.786 UTC First we need to name our process RP/0/7/CPU0:R1(config)#router isis LAB Then configure our Network Entity ( Area ) RP/0/7/CPU0:R1(config-isis)#net 49.0000.0000.0001.00 Then we assign the interfaces to the process, as…
