The following is an MIMP configuration example.
config>redundancy>multi-chassis
----------------------------------------------
peer 10.2.2.2 create
mc-ipsec
bfd-enable
tunnel-group 1 create
peer-group 2
priority 120
no shutdown
exit
exit
no shutdown
exit
The peer’s tunnel-group ID is not necessarily the same as the local tunnel-group ID. With bfd-enable, the BFD parameters are specified under the interface that the MIMP source address resides on, which must be a loopback interface in the base routing instance. The default source address of MIMP is the system address.
The keep-alive-interval and hold-on-neighbor-failure define the MIMP alive parameter, however, BFD could be used for faster chassis failure detection.
The SR OS also provides a tools command to manually trigger the switchover, for example:
tools perform redundancy multi-chassis mc-ipsec force-switchover tunnel-group 1
