Redistribute

Scenario to verify BGP redistribute connected and redistribute static functionality with metric and route-map filtering options, for both iBGP and eBGP sessions.

Route redistribution injects routes from other sources into BGP:

  • redistribute connected: Injects routes for directly connected networks (interfaces). DUT0 uses a dummy interface (dum0) to create a connected route.

  • redistribute static: Injects static routes configured on the router. DUT0 uses a blackhole static route to create the redistributed route.

For each source type, three variants are tested:

  • Basic: Redistribute without options. DUT1 learns the route and installs it.

  • With metric: Redistribute with metric 100 (MED). DUT1 learns the route with the specified MED value visible in the BGP table.

  • With route-map: Redistribute with a route-map filter. Only routes matching the route-map criteria are redistributed; others are filtered out. DUT0 has two routes but only one matches the filter.

Each variant is tested with both iBGP (same AS) and eBGP (different AS) sessions.

Test BGP Redistribute

Description

Test BGP redistribute connected and static: basic (DUT1 learns the route), metric (DUT1 learns with MED 100), and route-map (only matching routes redistributed). Each variant tested with iBGP and eBGP.

Scenario

Example 1

Step 1: Set the following configuration in DUT0 :

set interfaces dummy dum0 address 192.168.10.1/24
set interfaces ethernet eth0 address 10.1.1.100/24
set protocols bgp 10 neighbor peer remote-address 10.1.1.1
set protocols bgp 10 neighbor peer remote-as 10
set protocols bgp 10 redistribute connected
