Example (bgp routes)
Enter the following command to display the entire BGP table of routes:
ip bgp_routes
Network/Mask Peer Rem Addr NextHop Address Org Loc Pref Best/Used
------------- ---------------- ---------------- --- ---------- ---------
4.0.0.0/8 3.3.3.2 3.3.3.2 IGP 8183 BEST/USED
As Path: SEQ 200
5.0.0.0/8 2.2.2.3 2.2.2.3 IGP 8183
As Path: SEQ 300
...
SLOT 2: Total Nets 2
SLOT 5: Total Nets 7
When you specify the -i, -p, or ip_address options for the ip bgp_routes
command, the resulting display specifies the total number of networks, plus the
following additional information:
• Multi-exit-disc (Multiple-exit discriminator) -- RFC1771 defines this as an
optional, nontransitive attribute that is a 4-octet, nonnegative integer. A BGP
speaker uses the value of this attribute to help discriminate among multiple
exits to a neighboring autonomous system (AS).
• Aggregator -- RFC1771 defines this as an optional transitive attribute of
length 6. The attribute contains the last AS number that formed the aggregate
route (encoded as 2 octets), followed by the IP address of the BGP speaker
that formed the aggregate route (encoded as 4 octets).
