Configuring RSVP in GMPLS
RSVP-TE must be enabled on the SR OS towards the adjacent UNI-N in order to configure a
GMPLS label-switched path (gLSP).
RSVP parameters specific to GMPLS are configured under the config>router>gmpls
context.
This creates a new instance of RSVP for use in GMPLS signaling.
Global parameters for GMPLS are configured as follows:
config
router
gmpls
no gmpls
peer peer-cp-node-id
gr-helper-time max-recovery recovery-interval max-restart restart-interval
no gr-helper-time
keep-multiplier number
no keep-multiplier
no rapid-retransmit-time
rapid-retransmit-time hundred-milliseconds
no rapid-retry-limit
rapid-retry-limit limit
no refresh-time
refresh-time seconds
no refresh-time
lsp-init-retry-timeout seconds
no lsp-init-retry-timeout
no shutdown
shutdown
The default max-restart interval for GMPLS is 180 seconds.
The LMP Peer is configured under config>router>gmpls>peer peer-cp-node-id, where the
peer-cp-node-id is control plane identifier of the adjacent optical cross connect (UNI-N node).
RSVP uses the destination address returned by LMP for this peer control plane node ID as the
destination address, and the loopback address referenced under config>router>lmp>gmpls-
loopback-address local-gmpls-loopback-address as the local router ID to use for the session.
RSVP will come up if at least one IPCC is up.
RSVP hellos and support for graceful restart helper functionality are supported. RSVP
Graceful Restart Helper procedures implemented by the 7x50 also apply when the IPCC goes
down and comes back up, or when the neighboring peer control plane restarts.
The following CLI tree is used for configuring RSVP parameters for each LMP peer:
config
router
gmpls
