bridge domain issue

[marvin.dy]

Hi,

Im Currently using a 4431 router configuring it with a bridge domain. Im encountering problems with the bridge domain interface not able to ping my load balancer IP address.

We have one 4431 router connected to 2 2960 switches with 2 F5 connected to both of the switches also.

Below is my configuration for the bridge domain:

interface BDI1
 ip address 192.168.1.219 255.255.255.224
 no ip redirects
 no ip unreachables
 no ip proxy-arp
 no cdp enable

interface GigabitEthernet0/0/1
 no ip address
 no ip redirects
 no ip unreachables
 no ip proxy-arp
 negotiation auto
 service instance 1 ethernet
  encapsulation untagged
  bridge-domain 1
 
interface GigabitEthernet0/0/2
 no ip address
 no ip redirects
 no ip unreachables
 no ip proxy-arp
 negotiation auto
 service instance 1 ethernet
  encapsulation untagged
  bridge-domain 1

Im not able to ping my load balancer IP address:

sg-wr01#ping 192.168.1.220
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.1.220, timeout is 2 seconds:
.....
Success rate is 0 percent (0/5)
sg-wr01#ping 192.168.1.221
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.1.221, timeout is 2 seconds:
.....
Success rate is 0 percent (0/5)
sg-wr01#ping 192.168.1.222
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.1.222, timeout is 2 seconds:
.....
Success rate is 0 percent (0/5)

But when I change the bridge domain interface to a layer 3 interface I can ping the load balancer IP address:

interface GigabitEthernet0/0/1
 ip address 192.168.1.219 255.255.255.224
 no ip redirects
 no ip unreachables
 no ip proxy-arp
 negotiation auto
end

sg-wr01#ping 192.168.1.220
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.1.220, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/1 ms

sg-wr01#ping 192.168.1.221
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.1.221, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/1 ms

sg-wr01#ping 192.168.1.222
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.1.222, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/1 ms

Has anyone encountered this before?

Below is the network diagram:

Did you do a no shut on the BDI?

"The initial administrative state of a BDI depends on how the BDI is created. When a BDI is created at boot time in the startup configuration, the default administrative state for the BDI will be up, and will remain in this state unless the startup configuration includes the shutdown command. This behavior is consistent with all the other interfaces. When a BDI is created dynamically by a user at command prompt, the default administrative state is down."

Hi cehill,

I did a no shut on the BDI. The BDI interface is up.
