IOS-XR LDP Configuration memo – part 1

LDP Discovery Parameter

mpls ldp
 [vrf {VRF名}] router-id {IPアドレス}
 discovery {hello | targeted-hello} holdtime {秒}
 discovery {hello | targeted-hello} interval {秒}
commit

• 確認はshow mpls ldp parameters

LDP Discovery over a link

mpls ldp
 [vrf {VRF名}] router-id {IPアドレス}
 interface {インターフェース名}
commit

確認コマンド:

show mpls ldp discovery
show mpls ldp vrf {VRF名} discovery
show mpls ldp vrf all discovery summary
show mpls ldp vrf all discovery brief
show mpls ldp vrf all ipv4 discovery summary
show mpls ldp discovery summary all

• コンフィグガイドでは、インターフェース名はTE Tunnelを指定するとあるが、それ以外も指定できるっぽい
