The show ip bgp summary command output has the following limitations:
• If a BGP4 peer is not congured for an address-family, the peer information is not displayed.
• If a BGP4 peer is congured for an address-family but not negotiated for an address-family after the BGP4 peer is in the
established state, the show ip bgp summary command output shows (NoNeg ) at the end of the line for this peer.
• If a BGP4 peer is congured and negotiated for that address-family, its display is the same as in previous releases.
To view summary BGP4 information for the device, enter the following command at any CLI prompt

TABLE 94 show ip bgp summary output descriptions
This eld Displays
Router ID The device ID.
Local AS Number The BGP4 AS number for the device.
Confederation Identier The AS number of the confederation in which the device resides.
Confederation Peers The numbers of the local autonomous systems contained in the
confederation. This list matches the confederation peer list you congure
on the device.
Maximum Number of Paths Supported for Load Sharing The maximum number of route paths across which the device can balance
trac to the same destination. The feature is enabled by default but the
default number of paths is 1. You can increase the number from 2 through
8 paths.
Number of Neighbors Congured The number of BGP4 neighbors congured on this device, and currently
in established state.
Number of Routes Installed The number of BGP4 routes in the device BGP4 route table and the route
or path memory usage.
Number of Routes Advertising to All Neighbors The total of the RtSent and RtToSend columns for all neighbors, the total
number of unique ribout group entries, and the amount of memory used
by these groups.
Number of Attribute Entries Installed The number of BGP4 route-attribute entries in the device route-attributes
table and the amount of memory used by these entries.
Neighbor Address The IP addresses of the BGP4 neighbors for this device.
AS# The AS number.
State The state of device sessions with each neighbor. The states are from this
perspective of the device, not the neighbor. State values are based on the
BGP4 state machine values described in RFC 1771 and can be one of
the following for each device:
• IDLE - The BGP4 process is waiting to be started. Usually,
enabling BGP4 or establishing a neighbor session starts the
