Configure Software To Store Updates From Neighbor - Cisco NCS 5500 Series Configuration Manual

Configure BGP Neighbor Group and Neighbors
Clears a BGP neighbor.
• The * keyword resets all BGP neighbors.
• The ip-address argument specifies the address of the neighbor to be reset.
• The as-number argument specifies that all neighbors that match the autonomous system number be reset.
• The external keyword specifies that all external neighbors are reset.
The graceful keyword specifies a graceful restart.

Configure Software to Store Updates from Neighbor

Perform this task to configure the software to store updates received from a neighbor.
The soft-reconfiguration inbound command causes a route refresh request to be sent to the neighbor if the
neighbor is route refresh capable. If the neighbor is not route refresh capable, the neighbor must be reset to
relearn received routes using the clear bgp soft command.
Note Storing updates from a neighbor works only if either the neighbor is route refresh capable or the
soft-reconfiguration inbound command is configured. Even if the neighbor is route refresh capable and
the soft-reconfiguration inbound command is configured, the original routes are not stored unless the
always option is used with the command. The original routes can be easily retrieved with a route refresh
request. Route refresh sends a request to the peer to resend its routing information. The soft-reconfiguration
inbound command stores all paths received from the peer in an unmodified form and refers to these stored
paths during the clear. Soft reconfiguration is memory intensive.
