connectivity between two 6509

Hello

We have 6509 MLS on our campus Network and recently we have aquired another company who have also 6509 MLS in their own Network . Both the companies use different IP addressing scheme , different VTP domain name , Vlan's are different . We would like to make connectivity with new aquired company (between both 6509 ) and access the resources in both the ways . We don't want broadcast our VLAN info to their 6509 (of course VTP domain name is different ) . We can add their Network address on RIP table of our 6509 MSFC and vice versa . How about configuration 6509 Switch side ?. Should we enable Trunk on that particular port which will be used for connectivity or just enale the port only . FYI , port 1 on module 3 of our 6509 ( 3/1 ) will be used to connect to other 6509 through GBIC-ZX .

Thanks .

Raju

Re: connectivity between two 6509

You will be using a routed connection between the two switches. A trunk is not required for this, you could even get in trouble as trunking implicates exchanging vlan info. You do not want to do this.

Instead, configure the link on both sides as access interface and run a routing protocol to exchange routing tables. The vlan does not need to be the same on both sides when you don't use trunking. The ip/ipx networks must match.

You can see this solution as a very fast point-point serial link and it should be configured likewise.

Thanks Leo . Exactly , It's going to be serial point to point connection, here only it's through GBIC . How about configuration on Switch side (6509 ) ?. It is just a matter of enabling the port (3/1 ) and make connectivity and do the same the same configuration (enable the port ) on other 6509 .

Re: connectivity between two 6509

That is one part.

You should also put the ports in a separate vlan and define an IP adress on them. As stated previously these adresse must be in the same IP subnet.

So, you should create something like:

int vlan xx

ip address x.x.x.x 255.255.255.0

no shut

int gi3/1

switchport mode access

switchport access vlan xx

end

on both switches. You should also activate a routing protocol over the link.

Re: connectivity between two 6509

That's not entirely true, as switchport access vlan xx implies that you've entered the switchport command to make it an L2 port. You'll want to configure the IP address, but don't put that command I just mentioned in. You'll still want the switchport mode access command in there though. It will disable PAGP on that port and prevent your from accidentally creating a trunk port.
