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 Layer 3 Switch 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 Layer 3 Switch received better routes from other
sources (such as OSPF, RIP, or static IP routes).
• The routes that are unreachable because the Layer 3 Switch does not have a valid RIP, OSPF, or static route
to the next hop.
• Routes for a specific network advertised by the Layer 3 Switch 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 Layer 3 Switch has already sent it to the neighbor.
To display route information for a neighbor, use the following CLI methods.
ReTrans The number of sequence numbers that the Layer 3 Switch
retransmitted because they were not acknowledged.
UnAckSeq The current acknowledged sequence number.
IRcvSeq The initial receive sequence number for the session.
RcvNext The next sequence number expected from the neighbor.
SendWnd The size of the send window.
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.
