Job aid: ping and traceroute considerations

Ping and traceroute may fail for VRF, IPVPN, or MPLS routes if large packet sizes are used
for the operation. Do not use packet sizes larger than the following:
• Ping for VRF Lite: 1480 bytes
• Ping for IP VPN with MPLS: 1480 bytes
• Ping for IP VPN Lite: 1446 bytes
• Traceroute for VRF Lite: 1444 bytes
• Traceroute for IP VPN with MPLS: 1444 bytes
• Traceroute for IP VPN Lite: 1444 bytes
