GNS3 Cisco LAB : MPLS TE( Traffic-Engineering) FRR (fast-reroute) Link Protection.

Hello folks, In continuation of my previous blog on MPLS TE configuration, I have setup fast-reroute for MPLS TE tunnel so that if a designated primary link fails then the tunnel will take up the alternate path and the traffic loss will be avoided. Please check my previous blog for basic MPLS TE config in… Read More GNS3 Cisco LAB : MPLS TE( Traffic-Engineering) FRR (fast-reroute) Link Protection.

How MPLS Ping, MPLS Traceroute , MPLS Multipath trace can help in MPLS troubleshooting.

MPLS ping is a utility just like our old ipv4 ping in the hop to hop ip routing scenarios. The only difference is that it tells you that everything is fine in MPLS label switch path. In mpls label switch path you cannot rely on normal ping as it is possible that normal ping is working… Read More How MPLS Ping, MPLS Traceroute , MPLS Multipath trace can help in MPLS troubleshooting.

Cisco GNS3 Lab : Advertising IPv6 address over IPv4 MPLS/BGP Network.

In this example I am going to present a very simple configuration example for advertising ipv6 prefixes over IPv4 ISP transport network. This method is called 6VPE where we do not need any dual stack configurations and the transport network doesn’t need to be ipv6 aware. The whole concept becomes possible with the help of… Read More Cisco GNS3 Lab : Advertising IPv6 address over IPv4 MPLS/BGP Network.
