Displaying BGP4 information
26
This example shows how to display information for a specific neighbor, by specifying the neighbor’s
IP address with the command. None of the other display options are used; thus, all of the
information is displayed for the neighbor. The number in the far left column indicates the neighbor
for which information is displayed. When you list information for multiple neighbors, this number
makes the display easier to read.
The TCP statistics at the end of the display show status for the TCP session with the neighbor. Most
of the fields show information stored in the device’s Transmission Control Block (TCB) for the TCP
session between the device and its neighbor. These fields are described in detail in section 3.2 of
RFC 793, “Transmission Control Protocol Functional Specification”.
Syntax: show ip bgp neighbors [ <ip-addr> [advertised-routes [detail [ <ip-addr> [/ <mask-bits> ]]]] |
[attribute-entries [detail]] | [flap-statistics] | [last-packet-with-error] | [received
prefix-filter] |
[received-routes] | [routes [best] | [detail [best] | [not-installed-best] | [unreachable]] |
[rib-out-routes [
<ip-addr> / <mask-bits> | <ip-addr> <net-mask> | detail]] |
[routes-summary]]
The <ip-addr> option lets you narrow the scope of the command to a specific neighbor.
The advertised-routes option displays only the routes that the device has advertised to the
neighbor during the current BGP4 neighbor session.
