Type: PortList

Access: read-only

Description: List of router ports learned dynamically from PIM, DVMRP, MRDISC, MOSPF and IGMP/MLD Query messages on this VLAN

What is rlIgmpMldSnoopVlanRouterPortlist?

This read-only bitmask lists ports on this VLAN dynamically identified as leading to a multicast router, based on PIM, DVMRP, MRDISC, MOSPF, or IGMP/MLD query messages for either address family. An administrator inspects this to confirm the switch correctly discovered the uplink toward the multicast router in a dual-stack environment. For example, if IPv6 multicast isn't reaching the core router, checking rlIgmpMldSnoopVlanRouterPortlist confirms whether the expected uplink port was learned as a router port at all.

Examples
