MPLS LDP-IGP synchronization
1
By default, ldp-sync hold-down is disabled. To enable the ldp-sync hold-down timer with IS-IS, enter
the following commands:
Brocade(conf)# router isis
Brocade(config-isis-router)# address-family ipv4 unicast
Brocade(config-isis-router-router-ipv4u)# metric-style wide
Brocade(config-isis-router-router-ipv4u)# ldp-sync
Brocade(config-isis-router-router-ipv4u)# ldp-sync hold-down 100
By default, ldp-sync hold-down is disabled.To enable the ldp-sync hold-down timer with OSPF, enter
the following commands:
Brocade(conf)# router ospf
Brocade(conf-ospf-router)# ldp-sync
Brocade(conf-ospf-router)# ldp-sync hold-down 100
Syntax: ldp-sync hold-down seconds
The seconds parameter range is 1 to 65535 seconds.
Enabling LDP sync on an interface
Use the isis ldp-sync command under the conf-if-e-1/1 policy to enable the LDP sync feature on a
specific IS-IS interface. This overrides the global setting from the MPLS LDP-sync feature. By
default, the isis ldp-sync is not enabled individually on an interface.
Brocade(conf)# interface e 1/1
Brocade(conf-if-e-1/1)# ip router isis
Brocade(conf-if-e-1/1)# isis ldp-sync enable
Syntax: isis ldp-sync [enable | disable]
Use the ip ospf ldp-sync command under the conf-if-e-1/1 policy to enable the LDP sync feature
individually on an OSPF interface. By default, the ip ospf ldp-sync is not enabled individually on an
OSPF interface.
Brocade(conf)# interface e 1/1
Brocade(conf-if-e-1/1)# ip ospf area 0.0.0.0
Brocade(conf-if-e-1/1)# ip ospf ldp-sync enable
Syntax: ip ospf ldp-sync [enable | disable]
Setting the receive label silence timer
When labels are not received from the peer for a short period of time, the session is declared ‘In
Sync’. When a label is received from a peer, then the ‘receive label silence timer’ is reset.
Use the rx-label-silence-time command under config-mpls-ldp policy to define the length of the
receive label silence timer.
Brocade(conf)# router mpls
Brocade(config-mpls)# ldp
Brocade(config-mpls-ldp)# rx-label-silence-time 30000
Syntax: rx-label-silence-time value
