System Command Reference
Although this command is configured on a peer level, the warm-standby property is a nodal
characteristic. In other words, mixing of N:1 and 1:1 (hot standby) mode in the central standby node
is not supported. Consequently all peers on the central standby node must be configured for warm-
standby (N:1), or all peers must be configured for hot-standby (1:1) by omitting the warm-standby
keyword from the configuration.
The peer of the central-backup node is not aware of the redundancy model supported. In in other words,
the peer of the central-backup node does not know whether it peers with a warm-standby peer or host-
standby-peer. All nodes participating in this protection model must run SR OS R12.0 or higher.
This command applies only to the 7450 ESS and 7750 SR.
Default no warm-standby
Multi-Chassis Endpoint Commands
mc-endpoint
Syntax [no] mc-endpoint
Context config>redundancy>multi-chassis>peer
Description
This command specifies that the endpoint is multi-chassis. This value should be the same on both MC-
EP peers for the pseudowires that must be part of the same group.
The no form of this command removes the endpoint from the MC-EP. Single chassis behavior applies.
bfd-enable
Syntax [no] bfd-enable
Context config>redundancy>multi-chassis>peer>mc-ep
config>router>rsvp
config>router>bgp
config>router>bgp>group
config>router>bgp>group>neighbor
config>redundancy>multi-chassis>peer>mc-ep
Description This command enables the use of bi-directional forwarding (BFD) to control the state of the associated
protocol interface. By enabling BFD on a given protocol interface, the state of the protocol interface
is tied to the state of the BFD session between the local node and the remote node. The parameters used
for the BFD are set via the BFD command under the IP interface.
The no form of this command disables BFD.
Default
no bfd-enable
