Updating route information and resetting a neighbor session
Displaying all the routes received from the neighbor
To display all the route information received in route updates from a neighbor since you enabled
soft reconfiguration, enter a command such as the following at any level of the CLI.
Syntax: show ip bgp neighbors ip-addr received-routes [detail]
The detail parameter displays detailed information for the routes. The example above shows
summary information.
NOTE
The syntax for displaying received routes is shown. For complete command syntax, refer to
“Displaying BGP4 neighbor information”
NOTE
The show ip bgp neighbors ip-addr received-routes syntax supported in previous software releases
is changed to the following syntax: show ip bgp neighbors ip-addr routes.
Dynamically requesting a route refresh from
a BGP4 neighbor
You can easily apply changes to filters that control BGP4 routes received from or advertised to a
neighbor, without resetting the BGP4 session between the Layer 3 switch and the neighbor. For
example, if you add, change, or remove a BGP4 address filter that denies specific routes received
from a neighbor, you can apply the filter change by requesting a route refresh from the neighbor. If
the neighbor also supports dynamic route refreshes, the neighbor resends its Adj-RIB-Out, its table
of BGP4 routes. Using the route refresh feature, you do not need to reset the session with the
neighbor.
The route refresh feature is based on the following specifications:
•
RFC 2842. This RFC specifies the Capability Advertisement, which a BGP4 router uses to
dynamically negotiate a capability with a neighbor.
•
RFC 2858 for Multi-protocol Extension.
NOTE
The Brocade implementation of dynamic route refresh supports negotiation of IP version 4
unicasts only.
