Syntax loop-detect undo loop-detect Default Loop detection is disabled. Views LDP view, LDP-VPN instance view Predefined user roles network-admin mdc-admin Usage guidelines This command enables LDP to detect and terminate LSP loops.
Page 54: Maxhops
Default No LDP LSR ID is configured. LDP uses the MPLS LSR ID configured by the mpls lsr-id command for both the public network and VPN instances. Views LDP view, LDP-VPN instance view Predefined user roles network-admin mdc-admin Parameters lsr-id: Specifies an LDP LSR ID, in dotted decimal notation. Usage guidelines If you configure an LDP LSR ID by using the lsr-id command in LDP view or LDP-VPN instance view, LDP uses the LDP LSR ID.
Page 55: Md5-Authentication
mdc-admin Parameters hop-number: Specifies the maximum hop count for loop detection, in the range of 1 to 32. Usage guidelines LDP adds a hop count in a label request or label mapping message. The hop count increments by 1 on each LSR. When the hop count reaches the maximum hop count configured by this command, LDP considers that a loop occurs and terminates LSP establishment.
Page 56: Mpls Ldp
Usage guidelines To improve security for LDP sessions, you can configure MD5 authentication for the underlying TCP connections to check the integrity of LDP messages. The local LSR and the peer LSR must have the same key. Otherwise, they cannot establish a TCP connection.
Page 57: Mpls Ldp Timer
[Sysname-ldp] Related commands mpls ldp enable vpn-instance mpls ldp timer Use mpls ldp timer to set the Hello hold time, Hello interval, Keepalive hold time, and Keepalive interval.

Page 58 If the Hello hold time and the Keepalive hold time values are too large, LDP cannot quickly detect link failures. If the values are too small, LDP might mistakenly consider a normal link failed. As a best practice, use the default values. Make sure all links between two LSRs have the same Keepalive hold time as the one configured in LDP peer view when one of the following events occurs: •...

Usage guidelines An automatically created bypass tunnel can protect multiple primary CRLSPs. A bypass tunnel is unused when the bypass tunnel is not bound to any primary CRLSP. When a bypass tunnel is unused for the period of time configured by this command, MPLS TE removes the bypass tunnel to release the occupied bandwidth and tunnel interface number.
Page 146 The PLR uses the interface numbers in the specified range in ascending order for the bypass tunnels. When you use the tunnel-number command, follow these restrictions and guidelines: • The min-number must be smaller than or equal to the max-number. •...

Page 183: Peer
Predefined user roles network-admin mdc-admin Parameters number: Specifies the PSB and RSB timeout multiplier in the range of 3 to 255. Usage guidelines The PSB and RSB timeout is computed in this formula: Timeout = (keep-multiplier+0.5) × 1.5 × refresh-time. Refresh-time is the interval at which the peer device advertises the Path and Resv messages to the local device.
Page 184: Refresh Interval
If a matching neighbor exists and an authentication key has been configured for the neighbor, the device verifies the validity of the message according to the key. Otherwise, the device uses the authentication key configured in interface view or RSVP view to verify the message validity. If no authentication key is configured in any view, the device ignores the authentication object carried in the message and accepts the message.
Page 185: Reset Rsvp Authentication
Usage guidelines This command performs the following actions: • Determines the interval for sending Path and Resv messages. • Adds the locally configured refresh interval in the sent Path and Resv messages, so the peer device can use this value to calculate the PSB and RSB timeout. Examples # Set the refresh interval for Path and Resv messages to 60 seconds.
