ipMcastRouteRtPrefixLength

Module: IPMCAST-MIB

OID (symbolic): IPMCAST-MIB::ipMcastRouteRtPrefixLength

OID (numeric): 1.3.6.1.2.1.168.1.5.1.16

Node type: OBJECT-TYPE

Type: InetAddressPrefixLength

Access: read-only

Description: The length in bits of the mask associated with the route used to find the upstream or parent interface for this multicast forwarding entry.

The InetAddressType is given by ipMcastRouteRtAddressType. For values 'ipv4' and 'ipv4z', this object must be in the range 4..32. For values 'ipv6' and 'ipv6z', this object must be in the range 8..128.

What is ipMcastRouteRtPrefixLength?

Gives the prefix length of the route used to compute the upstream interface for this multicast entry, paired with ipMcastRouteRtAddress to fully describe that underlying route.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.2.1.168.1.5.1.16
snmpwalk -v2c -c public <target> IPMCAST-MIB::ipMcastRouteRtPrefixLength

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.2.1.168.1.5.1.16.1
snmpget -v2c -c public <target> IPMCAST-MIB::ipMcastRouteRtPrefixLength.1
