Routing help

[PhoneTechMan]

Morning all, please take a look at my router configs and tell me I went wrong. I'm more on the voice side than data, and any help is appreciated.

Morning all, I'm setting up a new port network at a new location using a CMC, and I'm having a hard time getting the IPSI, CLAN & Medpro to back back to our 8710 at the main site. The IP scheme for the main is as follows: IPSI's-192.168.241.xxx, CLAN's & Medpro's-192.168.243.xxx, control network A-vlan 192.168.241.xxx, control network B-vlan 192.168.242.xxx. I've setup the CMC as such: IPSI-192.168.246.xxx, CLAN & Medpro-192.168.246.xxx. I'm pretty sure that my main issue is routing from the new location back to the main site. Here's the routes I have setup coming from both ways, please feel free to shoot holes in it:

Any and all help, suggestions, comments are greatly appreciated. Thanks In Advance.

i would say remove the

ip route 192.168.246.0 255.255.255.0 192.168.245.9
ip route 192.168.246.0 255.255.255.0 192.168.245.13

from the new site...

the route above them is a default route which will send all traffic that is not local to the main site...

i think if your main site has ip cef enabled it will load balance over the two t1's

if you want the same to occur at the new location you will need at the new location:

ip route 0.0.0.0 0.0.0.0 192.168.245.13


see if that helps..

Took those two out with the same effect. I am able to ping (somewhat, 3 of 5 received) the IPSI at the new location from the main. Any other suggestions?

 

[PhoneTechMan]

OK, another question: Can I extend one of the existing vlans, the .241 or .242 across to the new location? I'm sure it's possible, but have no clue on how to achive it. Thanks again...

Why not just bond the two T1 point to point serial together into one multilink interface on both sides?

Something like:


Main Router

interface Multilink1
description connected to remote sight
ip unnumbered Ethernet0/0
ppp multilink
no ppp multilink fragmentation
multilink-group 1
!
interface Ethernet0/0
description connected to lan
ip address 198.263.243.100 255.255.255.0
full-duplex
!
interface Serial0/0
description multilink 1 interface
no ip address
encapsulation ppp
no keepalive
no fair-queue
ppp multilink
multilink-group 1
!
!
interface Serial0/1
description multilink 1 interface
no ip address
encapsulation ppp
no keepalive
no fair-queue
ppp multilink
multilink-group 1
!
ip route 0.0.0.0 0.0.0.0 192.168.243.254
ip route 192.168.246.0 255.255.255.0 multilink1



Remote Router

interface Multilink1
description connected to remote sight
ip unnumbered FastEthernet0/0
ppp multilink
no ppp multilink fragmentation
multilink-group 1
!
interface FastEthernet0/0
description connected to lan
ip address 198.263.246.1 255.255.255.0
speed 100
full-duplex
!
interface Serial0/0
description multilink 1 interface
no ip address
encapsulation ppp
no keepalive
no fair-queue
ppp multilink
multilink-group 1
!
!
interface Serial0/1
description multilink 1 interface
no ip address
encapsulation ppp
no keepalive
no fair-queue
ppp multilink
multilink-group 1
!
ip route 0.0.0.0 0.0.0.0 multilink1

 

[JOAMON]

With this in place you will also effectively double the BW between sights.

 

[PhoneTechMan]

Thanks, I'll try this out, and let you know if it works.

 

[JOAMON]

There is one correction on one command:

multilink-group 1

should be ppp multilink-group 1

Also I did not list but remember to apply:

service-module t1 clock source internal
to both serials on one router...not the multilink interface.
