Hi,
I have a question about Path protection in Juniper routers(To be clear
iam not talking about fast reroute).Junos provides the concept of
secondary LSP which is can be used for data traffic when the primary LSP
is not reachable.Can this be taken as Path protection?
And how does the ingress router know that the primary path is not
available? And does junos implement
draft-chang-mpls-path-protection-02.txt?
And also does junos support node protection?
Thanks in advance,
Krishna
