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

Hi,
R1 and R4 have no route back to 3.3.3.0 network. you can use static routes or redistribute this connected interface into OSPF in your AS.
