[c-nsp] traceroute through 6PE -- icmp6 message sourcing

[James Jun]

Hi List,

 

With 6PE, when P routers have 'ipv6 unicast-routing' turned on, they will
show up on traceroute using ::FFFF:ipv4.  I've noticed that on a number of
networks lately (i.e. AT&T, Cogent, etc), IPv6 interface hops are starting
to show up on traceroute with respective MPLS label tags.

 

Is there a way to make the P routers source their ICMP message from
something other than ::FFFF:ipv4 when using 6PE?  I've tried putting on IPv6
IP's as /128 on the MPLS P pathway, but to no effect.  Or is this something
that doesn't work in IOS, but only works on IOS XR?

 

Thanks in advance!
