Displaying BGP4 information

Displaying route information for a neighbor
You can display routes based on the following criteria:
•
A summary of the routes for a specific neighbor.
•
The routes received from the neighbor that the device selected as the best routes to their
destinations.
•
The routes received from the neighbor that are the best BGP4 routes to their destinations, but
were nonetheless not installed in the IP route table because the device received better routes
from other sources (such as OSPF, RIP, or static IP routes).
•
The routes that are unreachable because the device does not have a valid RIP, OSPF, or static
route to the next hop.
•
Routes for a specific network advertised by the device to the neighbor.
•
The Routing Information Base (RIB) for a specific network advertised to the neighbor. You can
display the RIB regardless of whether the device has already sent it to the neighbor.
Displaying summary route information
To display summary route information, enter a command such as the following at any level of the
CLI.
TotalRcv The number of sequence numbers received from the neighbor.
DupliRcv The number of duplicate sequence numbers received from the neighbor.
RcvWnd The size of the receive window.
SendQue The number of sequence numbers in the send queue.
RcvQue The number of sequence numbers in the receive queue.
CngstWnd The number of times the window has changed.
