Command Parameters
- ip-address WORD<0-255>
- Specifies the IP address.
- priority <0-7>
- Specifies the priority. The
default is 7.
- source-mode nodal

nodal. Nodal MPs provide both MEP and MIP functionality for SPBM deployments.
Nodal MPs are associated with a B-VLAN and are VLAN encapsulated packets. The
default is nodal.
- source-mode smltVirtual
- Specifies the source mode of
smltVirtual. The switch supports SMLT interaction with SPBM. The platform uses two
B-VIDs into the core from each pair of SMLT terminating nodes. Both nodes
advertise the Nodal B-MAC into the core on both B-VIDS. In addition each node
advertises the SMLT virtual B-MAC on one of the two B-VLANs. The default is
nodal.
- ttl-value <1-255>
- Specifies the time-to-live (TTL)
value. The default is 64.
- vrf WORD<1-16>

If you use this command on a DvR Leaf node, the output only shows DvR Controller IP
addresses if the IP address or host route specified is unknown in the DvR domain.
