Module: Wellfleet-OSPF-MIB
OID (symbolic): Wellfleet-OSPF-MIB::wfOspfASEMcastEnable
OID (numeric): 1.3.6.1.4.1.18.3.5.3.2.3.1.30
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: This attribute indicates whether AS External routes are multicast capable. If enabled, the advertising ASBR sets the MC-bit in the ASE-LSAs for those routes, so that they can be used for multicast purpose.
If an MOSPF router works as an ASBR to support IGMP Relay, it should has this attribute set to 'enabled'.
By default, all external routes are multicast incapable. If it's known that an ASBR's external routes can only be used for unicast, this attribute must be set to 'disabled' on the ASBR.
For example, if an ASBR has a BGP connection to an ISP but the routes learned via BGP can't be used for multicast because external multicast traffic should be injected by another router with a DVMRP tunnel to Mbone, this attribute on the ASBR should be set to 'disabled'.
What is wfOspfASEMcastEnable?
Marks whether this router's redistributed AS-external routes should be flagged as multicast-capable (the MC-bit) in the ASE-LSAs it originates, letting MOSPF use them for multicast RPF checks. It should be enabled on an ASBR that's relaying IGMP for multicast sources reached via those external routes, but left disabled if the external routes (e.g. a BGP feed) can only legitimately carry unicast traffic.
