Can't ping other BGP AS

Dear,

I'm trying out a configuration with BGP and OSPF. See below

I can't ping from R5 to R4 and R1 and reverse. Or is it that when I'm in another AS I can't ping? I tried to add a route to subnet 3.3.3.0/24 but it doesn't work either.

### IP ROUTE from R5 ###

      2.0.0.0/24 is subnetted, 1 subnets

B        2.2.2.0 [20/0] via 3.3.3.1, 01:17:55

      3.0.0.0/8 is variably subnetted, 2 subnets, 2 masks

C        3.3.3.0/24 is directly connected, FastEthernet1/0

L        3.3.3.2/32 is directly connected, FastEthernet1/0

      4.0.0.0/24 is subnetted, 1 subnets

B        4.4.4.0 [20/2] via 3.3.3.1, 01:14:49

### IP ROUTE from R1 ###

      2.0.0.0/24 is subnetted, 1 subnets

O IA     2.2.2.0 [110/2] via 4.4.4.2, 00:28:37, FastEthernet5/0

      4.0.0.0/8 is variably subnetted, 2 subnets, 2 masks

C        4.4.4.0/24 is directly connected, FastEthernet5/0

L        4.4.4.1/32 is directly connected, FastEthernet5/0

The configuration can be found in attachment.

I tried to add the routes/networks in BGP on the R1, R4 and R3 but the ICMP doesn't work either.

This is the show version:

Hi,

You must get the 3.3.3.0/24 network into OSPF so here are 2 ways to achieve this.

on R3:

route-map REDIS_CONN

match interface f5/0

router os 1

redistribute connected subnets route-map REDIS_CONN

another way:

router os 1

netw 3.3.3.0 0.0.0.255 a 1

passive-interface f5/0

Regards

Alain
