Merging two Networks

Hello All,

My company has acquired a smaller company that has a Fios connection and Sonicwall 2040 as their sole connection. They are utilizing an address scheme of 10.0.0.x. My network uses a 192.168.x.x network and BGP/IPFR to network all of the remote locations. I have my new router and full t1 plugged in at this new location with an 1841 router one ethernet port is configured w/ 10.0.0.2 and one w/ 192.168.110.1

Problem is getting them to see the 100.1.x.x network back at my home office. I have setup a static route on the Sonicwall and on my ATM router. But the when I do a trace route the traffic dies off when it hits the BGP network. Do I need to contact my ISP? Is the IPFR set up to only forward 192.168 traffic? (See attached diagram)

Re: Merging two Networks

Hello,

You added the 10.0.0.0/24 network on the wrong server as far as I can see. You need to ad it on the loveland router not on the atm router.

Re: Merging two Networks

Hello,

Does the route towards 100.1.X.X appears on the loveland_ground_masters router?

Re: Merging two Networks

The Loveland router connects to the 100.1.x.x network via BGP. The route is advertised via BGP

Sample of SH BGP command.

Network Next Hop Metric LocPrf Weight Path

*> 0.0.0.0 192.168.252.149 0 13979 65000 i

*> 100.1.0.0/16 192.168.252.149 0 13979 65000 i

*> 192.168.1.0 192.168.252.149 0 13979 65000 i

Type escape sequence to abort.

Tracing the route to 100.1.1.41

1 192.168.252.149 8 msec 8 msec 8 msec

2 192.168.254.2 [AS 13979] 48 msec 48 msec 48 msec

3 100.1.1.41 [AS 65000] 68 msec 52 msec 48 msec

Re: Merging two Networks

Is it possible to manually define the next hop attribute in BGP?

I've defined the 10 network under my BGP on my 1841 (loveland) router.

router bgp 65110

no synchronization

bgp log-neighbor-changes

network 10.0.0.0 mask 255.255.255.0

neighbor 192.168.252.149 remote-as 13979

neighbor 192.168.254.2 remote-as 65000

no auto-summary

So it advertises the 10.0.0.x network now when i do the SH BGP command:

Network Next Hop Metric LocPrf Weight Path

*> 0.0.0.0 192.168.252.149 0 13979 65000 i

*> 10.0.0.0/24 0.0.0.0 0 32768 i

*> 100.1.0.0/16 192.168.252.149 0 13979 65000 i

*> 192.168.1.0 192.168.252.149 0 13979 65000 i

*> 192.168.10.0 192.168.252.149 0 13979 65010 i

But it has a next hop of 0.0.0.0

Re: Merging two Networks

Hello,

Is on your ATM router the way back to 10.0.0.0/24 known? Did you add the 10.0.0.0/24 network on the loveland router in your BGP AS?

Re: Merging two Networks

on the ATM Router i'm unable to get to the 10 network either.

When I do a traceroute back to the 10 network it dies off when it hits the IPFR/BGP

BRICK_ATM#traceroute 10.0.0.2

Type escape sequence to abort.

Tracing the route to 10.0.0.2

1 192.168.254.1 12 msec 12 msec 20 msec

2 192.168.254.2 28 msec 24 msec 28 msec

3 * * *

I specified a manual route statement.

ip route 10.0.0.0 255.255.255.0 192.168.252.149

As well as defining the 10.0.0.x network in the Router BGP Statement:

router bgp 65000

no synchronization

bgp log-neighbor-changes

network 0.0.0.0

network 10.0.0.0 mask 255.255.255.0

network 100.1.0.0 mask 255.255.0.0

network 192.168.0.0

network 192.168.1.0

neighbor 10.0.0.2 remote-as 65110

neighbor 192.168.252.150 remote-as 65110

neighbor 192.168.254.1 remote-as 13979

neighbor 192.168.254.34 remote-as 65017

neighbor 192.168.254.182 remote-as 65054

no auto-summary
