Session Parameters Commands
session-parameters
Syntax session-parameters
Context config>router>ldp
Description This command enables the context to configure peer specific parameters.
peer
Syntax [no] peer ip-address
Context config>router>ldp>session-parameters
Description This command configures parameters for an LDP peer.
Default none
Parameters ip-addr — The IPv4 or IPv6 address of the LDP peer in dotted decimal notation.
adv-adj-addr-only
Syntax [no] adv-adj-addr-only
Context config>router>ldp>session-parameters>peer
Description This command provides a means for an LDP router to advertise only the local IPv4 or IPv6 interfaces
it uses to establish hello adjacencies with an LDP peer. By default, when a router establishes an LDP
session with a peer, it advertises in an LDP Address message the addresses of all local interfaces to
allow the peer to resolve LDP FECs distributed by this router. Similarly, a router sends a Withdraw
Address message to of all its peers to withdraw a local address if the corresponding interface went
down or was deleted.
This new option reduces CPU processing when a large number of LDP neighbors come up or go
down. The new CLI option is strongly recommended in mobile backhaul networks where the number
of LDP peers can be very large.
The no form of this command reverts LDP to the default behavior of advertising all local interfaces.
