Cisco issues !!!

Hi All!

I have a lil problem with a vendor's network.

Network 10.46.x.x is connected to my vendor network. And
Network 10.46.x.x is the only network that is allowed to connect to the vendor. I added a 10.4.x.x network. So how can I get the 10.4.x.x to talk with my vendor? Should I create a NAT pool on the Cisco Catalyst 6509?

---------------------------
| Vendor(10.46.61.72)
----------------------------
^
|
|
5500 switch
^
|
Catalyst 6509
|
|
---> (10.4.x.x)Added Network*Needs to be connected to vendor
^

--------------------
(10.46.x.x)
My Network
--------------------

Any Ideas will help!!! Thanks!!! =)

if your 10.4.x.x is connected to a port on 6509 and your 10.46.x.x is connected to another port, yes you can create a NAT on 6509. But this NAT should cover both networks.

what you also can do is, on the router module of 6509 and 5500, configure an EIGRP (or RIP2) and subnet 10.46.x.x with VLSM (in other words extend the current subnetmask, 255.255.0.0, a few bits) so you can have 2 subnets within the subnet 10.46.x.x remember only your 6509 and 5500 are supposed to know this new subnet mask.

If I were in the situation, I would use VLSM because NAT costs a lot of CPU resourse.

I have a discription of subneting subnets in Heather's thread "vslm" in this forum.

Which one? NAT or VLSM?

Actually the NAT works well... havent tried VLSM yet, but the idea sounds reasonable and makes sense. I will try it later on when the traffic is to a minimal =) Thanks Again!!!

National Agency Timing?

hi
tell me steps to configure NAT in router 6590
(basic steps)

can we configure NAT in 3500 router???

regards

you can configure nat in most routers, it's not such an advanced feature. I really don't remember the specific commands cuz I haven't touched routers for a year. you can check out cisco's NAT documentation:
