MPLS VPN: VRF

MPLS VPN building blocks 1. Virtual routing and forwarding (VRF) - This creates logical routing instance, each virtual instance is separated such that virtual instances to instances are not reachable. 2. MP-BGP - BGP is extended to distribute MPLS VPN tags. 3. IGP - OSPF or IS-IS among the MPLS LSRs. 4. MPLS - Using … Continue reading MPLS VPN: VRF

VRF-Lite: Experiment with real gear

Continue from my previous blog post about VRF-lite. This time I am trying with real gear to test out. No route in actual routing table RXC#sh ip route Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP D - EIGRP, EX - EIGRP external, O - OSPF, IA … Continue reading VRF-Lite: Experiment with real gear

VRF-Lite: Applying VRF-lite to segregate different traffic for different destination

This configuration is done only on router (RXC). The objective is to segregate the traffic between two vlans, for vlan 10 the traffic will go towards Production internet and vlan 20 will go towards Guest internet. Virtual routing and forwarding (VRF) is very similar to vlan, except VRF is for layer 3. The two traffics … Continue reading VRF-Lite: Applying VRF-lite to segregate different traffic for different destination
