[c-nsp] Ping with vrf intermittent but ping mpls normal

[nanda pradana ramadhan putra]

Hi Oliver,


The topology like this JKT-PAJAK-C3750-UPE-01 - MPLS CLOUD
- JATENG-UNGARAN-R7606-NPE-01 - JATENG-GI.RAWALO-R3845-UPE-01
The ping is just from gateway vrf on pajak to gateway vrf on rawalo the
result is always have RTO on it. But ping vrf from pajak to ungaran the
result is OK. The user on pajak said that they always have packet loss when
trying to reach user on rawalo. I've investigated it and created new vrf on
rawalo but the result still same RTO always occur. the other issue when i
ping using all vrf on rawalo to the other remote site is always RTO. Can be
it caused by transmission problem? ungaran is upstream path for rawalo.
Ping p2p interface from ungaran to rawalo always good. The connection is
using L2DWDM broadcast.

if it caused by ICMP limiter what kind of CoPP that jusl limit icmp ping
just on vrf? but user also have rto i think it is not caused by CoPP

i try to without mpls just ping using its loopback the result is smooth
rather ping vrf

JKT-PAJAK-C3750-UPE-01#ping 202.162.222.241 repeat 1000

Type escape sequence to abort.
Sending 1000, 100-byte ICMP Echos to 202.162.222.241, timeout is 2 seconds:
