Next up is MPLS VPN; actually VPNv4 routes are what these actually are since we are only passing IPv4 traffic in this example. So we have this diagram below – CE1 and CE2 are the customer routers and both are running OSPF in Area 0.  They need to talk to each other but do not…

Ok, time for some MPLS!  For this lab I will be using the OSPF routing protocol first, then we can move to IS-IS next.  All we will be doing here is configuring LDP First up, lets enabled LDP on all OSPF interfaces.  Normally you would do this under each interface, but here we will use…

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…
