ZXR10 8900 series switch are as follows:
� When mpls ldp router-id command is used to designate ad-
dress of an interface as router ID, and an interface has an IP
address and is in UP status, this interface will serve as the
router ID.
� Otherwise, when there are loopback interfaces configured with
an IP address, maximum IP address among the IP addresses
of all loopback interfaces will serve as router ID.
� Otherwise, maximum IP address of an interface in UP status is
selected as router ID.
When force keyword is configured, router ID designated by m
pls ldp router-id command will come into use when next router
ID selection occurs. Router ID selection occurs at the following
situations:
� LDP restarts.
� Interface with address used by current router ID shuts down.

not configured.
When force keyword is configured, effect of the command mpls
ldp router-id depends on the current status of the designated in-
terface.

addresses are not the current router ID. Router will force router
ID to change into designated value, intermit current session,
free label studied in the session and intermit the MPLS trans-
mission relating to binding with labels.

it turns to UP. Router will force router ID to change into des-
ignated value, intermit current session, free label studied in
