Access: read-only
Description:
The value of vRtrIcmp6InPktTooBigs indicates the number of ICMP Packet Too Big messages received by this router instance.
What is vRtrIcmp6InPktTooBigs?
This read-only counter increments each time the router instance receives an IPv6 ICMPv6 Packet Too Big message, which signals that a neighbor has a smaller MTU than expected. Packet Too Big errors help with Path MTU Discovery, allowing the router to adjust transmission size for specific routes; operators monitor this counter to detect MTU mismatches in the network. High counts may indicate misconfigured link MTU values.
