We have a wireless bridge connected to a router.
The the router whose f/e address 192.168.255.130 which is also the gateway of the bridge
The Bridges IP is 192.168.255.132
I am unable to telnet or even trace to that bridge from the gateway/router.
When I try and trace to it, I get sent out into our providers network
However I CAN ping !
router #ping 192.168.255.132
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.255.132, timeout is 2 seconds:

Now from the bridge....I fail to ping the gateway

router#sh ip int br
FastEthernet1/1 192.168.255.130 YES NVRAM up up
bridge#sh ip int br

Does this make any sense?

The bridge BVI and the f/e interface on your "router" are on the same subnet, right? Since you're calling the f/e the default gateway for the bridge, I imagine this is the case. A /24 mask maybe? Yes?
So what is "ROUTER5" and why do you get a /30 mask when you do a route lookup to the same address?
ROUTER5#sh ip route 192.168.255.132 <-----BRIDGE IP (Are you sure???)
Routing entry for 192.168.255.132/30
You need to look into this and/or give us more information to help you out.

yes..they should be in the same subnet
Bridge#sh run interface BVI1
Building configuration...
Current configuration : 83 bytes
!
interface BVI1
ip address 192.168.255.132 255.255.255.0
no ip route-cache
end
Router#interface FastEthernet1/1
ip address 192.168.255.130 255.255.255.248
no ip route-cache
ip ospf cost 7
ip ospf hello-interval 5
ip ospf dead-interval 30
duplex auto
speed auto
no cdp enable
end
However,
I have no problem logging into the client
end of the Bridge...Bridge B so to speak
The subnet masks are different on that and its gateway too
ROUTER B#sh running-config interface fastEthernet 0/1
Building configuration...
Current configuration : 191 bytes
!
interface FastEthernet0/1
ip address 192.168.255.129 255.255.255.248
ip ospf cost 1851
ip ospf hello-interval 5
ip ospf dead-interval 30
load-interval 30
duplex auto
speed auto
end
BRIDGE B
BRIDGEB#interface BVI1
ip address 192.168.255.131 255.255.255.0
no ip route-cache
end
The masks for brige B and its gateway are different too.
And the only way i can telnet into bridge A
is to go through Bridge B (wireless)
I am pulling cdp from all devices

here is what happens when i do a show ip route to the remote end bridge from the gatweay in question
router#sh ip route 192.168.255.131
