[j-nsp] Path MTU Discovery - MPLS VPN

[masood at nexlinx.net.pk]

path mtu check requires at least one IP address must be associated with
each vrf. If an IP address is not associated with the routing instance, 
icmp reply messages cannot be sent.

> Hi,
>
> I've been trying to  get Path MTU Discovery working for M/J-series,
> appreciate that the M-series requires vrf-mtu-check <id-10380545.html>
> setting. Having done this I've tried testing it by launching Pings (DF
> set) with a larger MTU than the link, but I'm getting no response at all
> - expecting ICMP response.
> Has anyone any experience of the above? What stops it from working? - I
> have vrf-table-label set on some CE/PE devices. Is my test valid?
> Thanks,
> Tim.
