Default Route not redistributing - BGP

[snarayanaraju]

Hello Guys - I am trying to figure out why static default route is not getting redistributed to any peers (eBGP and iBGP). However, other static routes are getting redistributed. Can i know where is the issue. Thank you in advance

Hi Sairam,

It could be due to below.

Router-02#show ip route
Gateway of last resort is 192.168.0.4 to network 0.0.0.0 <<<

S* 0.0.0.0/0 [1/0] via 10.27.0.4 <<<

Can you try removing below route and check?

Gateway of last resort is 192.168.0.4 to network 0.0.0.0

Please rate if it helped.

Hello
Is this a direct ibgp peer or via some igp?
I would expect to see from the originating router in the advertised route output at least the physical connected links and also the 8.8.4.4 route especially with you redistributing static/connected

The default static wont show up here as you are advertising it via the neighbor default originate,, So as its originating locally it not subject to the redistribute static

On the receiving router can you post
sh ip bgp neighbors x.x.x.x routes

Can you perform a soft reset on the neighbors?

Clear ip bgp * soft
sh ip bgp sum
sh ip bgp

Thank you all.

The best route to 0.0.0.0 is not via 10.27.0.4. Can you please share the output of: show ip cef 0.0.0.0 

I think BGP is NOT sending default route from redistribution since the static default route is NOT the best route for the router.

Hello

With the default originate it should advertise th default irrespective if a route is in n the rib or not
