[mpls-linux-general] Regarding mpls 1.0

[<um...@de...>]

Hi all,
I have one doubt in mpls 1.0 version regarding mpls patch in
rt_set_nexthop in route.c.

1)In this we are putting the patch only if we have the fib info
available.that means we are sure fib info is available in case of mpls ,
but how ?
2)Under if (fi) , there is one more checking for mtu ==0 , then we are
assiging pmtu.What if mtu is not zero ??

Thanks and Regards
uma
