Cisco HSRP vs MPLS Fast Re-route

[Carlton Patterson]

Hello Experts,

I know the HSRP and MPLS FRR are two different technologies, however their aim to solve the same issue of recovery in the event of a failure.

Can someone please tell me (or provide a link) where I can find information on the benefits and advantages or disadvantages of using MPLS FRR over HSRP?

If you are knowledgeable to know the answer then I would love to hear your views.

Really appreciate your help with this one.

Cheers

Carlton

In my own opinion, I don't think you can compare the two.

HSRP is much more localized to a set of routers. FRR requires a pretty comprehensive MPLS traffice engineering build.

You see this in large service provider networks.

Agreed to vmiller. They are totally different technology / feature. HSRP is a First-hop redundancy protocol. Whereas FRR is a mechanism to protect MPLS TE LSPs from a node / path failure.

So, comparing these two feature is not worth, IMHO too.
