Total number of BGP routes (NLRIs)

The number of BGP4 routes the routing switch has installed in the

Installed

BGP4 route table.

 

 

Distinct BGP destination networks

The number of destination networks the installed routes represent.

 

The BGP4 route table can have multiple routes to the same network.

 

 

Routes originated by this router

The number of routes in the BGP4 route table that this routing switch

 

originated.

 

 

Routes selected as BEST routes

The number of routes in the BGP4 route table that this routing switch

 

has selected as the best routes to the destinations.

 

 

BEST routes not installed in IP

The number of BGP4 routes that are the best BGP4 routes to their

forwarding table

destinations but were not installed in the IP route table because the

 

routing switch received better routes from other sources (such as

 

OSPF, RIP, or static IP routes).

 

 

Unreachable routes (no IGP route for

The number of routes in the BGP4 route table whose destinations are

NEXTHOP)

unreachable because the next hop is unreachable.

 

 

IBGP routes selected as best routes

The number of “best” routes in the BGP4 route table that are IBGP

 

routes.

The number of “best” routes in the BGP4 route table that are EBGP

 

routes.

 

 

USING THE WEB MANAGEMENT INTERFACE

You cannot display summary route information using the Web management interface.

Displaying the BGP4 Route Table

BGP4 uses filters you define as well as the algorithm described in “How BGP4 Selects a Path for a Route” on page 10-3to determine the preferred route to a destination. BGP4 sends only the preferred route to the router’s IP table. However, if you want to view all the routes BGP4 knows about, you can display the BGP4 table using either of the following methods.
