Ok, time for some VRF lite basics and we can throw in some Dot1Q trunks to go with it. First, let’s create our VRF called LAB RP/0/7/CPU0:R1(config)#vrf LAB Now we need to enable the address family for this VRF, there IPv4 Unicast RP/0/7/CPU0:R1(config-vrf)#address-family ipv4 un RP/0/7/CPU0:R1(config-vrf-af)#exit Now we need to enable the IPv6 address family…
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…
