BGP stores route information on the AVL tree and this command retrieves that information. Information in the AVL tree is not sorted. The information returned by this command will not be displayed in any particular order.

Procedure

To enter User EXEC mode, log on to the switch.
Display information about BGP routes:

show ip bgp route [<prefix/len>] [community <enable|disable>] [ip {A.B.C.D}] [longer-prefixes] [vrf WORD<1–16>] [vrfids WORD<0–512>]

Variable Definitions

The following table defines parameters for the show ip bgp route command.


Variable	Value
community <enable\|disable>	Enables or disables the display of community attributes.
ip {A.B.C.D}	Specifies an IP address.
longer-prefixes	Shows long prefixes. Longer-prefixes indicates the mask length from a specified prefix to 32 (for example, show from prefix a.b.c.d/len to a.b.c./32).
<prefix/len>	Shows paths with this prefix. The prefix is the IP address and exact mask length (must be an integer value from 0–32).
vrf WORD<1–16>	Specifies a VRF instance by name.
vrfids WORD<0–512>	Specifies a range of VRFs by ID number.

Table 1. show ip bgp route
Field	Description
NETWORK/MASK	Specifies the path prefix address.
PEER REM ADDR	Specifies the remote peer address.
NEXTHOP ADDRESS	Specifies the BGP next hop address.
ORG	Specifies the source of a route: IGP — the route is interior to the originating AS that inserts this route into the BGP table (0 = IGP). EGP — the route is learned through an Exterior Gateway Protocol (EGP) before it is inserted into the BGP table (1 = BGP). Incomplete — the origin of the route is unknown or learned by some other means. For example, the router learns these routes through RIP, OSPF, or static routes (2 = Incomplete).
LOCAL PREF	Specifies the local preference.
