Alcatel Unleashed

Hi Everyone,

I need to connect 6850 switch to 7750.
6860 switch will have subnet for management as 192.160.50.0 this is new subnet which is not yet in our 7750

setup is

6850 with management IP 192.168.50.1----------------Direct connection to 7750 subnet 192.168.60.0-----------7750
Where as 192.168.60.0 is new subnet between 6850 and 7750.

This 7750 is our Core MPLS and it connects and nei to 4 more MPLS.These all 4 7750 are our core MPLS.

Need to know which type of config I can do so that users from our core can reach new subnet 192.168.50.1?

Also 7750 has VPLS service for 192.168.70.0 network and I want to extend this to 6850? how can I do that?

Regards
Mike

Hi.
Just to try to understand what you are trying to accomplish;

Your OS6850 has an IP interface of 192.168.50.1, and you want this network to be reachable via the 7750 SR platform.
Linknet to be used between 6860 and 7750 is 192.168.60.0.


I would make the port on 7750 towards 6850 a hybrid dot1q port.

A:SR03# \configure port 1/1/4
A:SR03>config>port# info
----------------------------------------------
shutdown
ethernet
exit
----------------------------------------------
A:SR03>config>port# ethernet mode hybrid
*A:SR03>config>port# info
----------------------------------------------
ethernet
mode hybrid
encap-type dot1q
exit
no shutdown
----------------------------------------------

Create a router interface on 7750 and assign this the linknet address, and port x/y/z:vlanID.

Create the same VLAN on 6850 and bind this to an IP interface with the 6850 linknet address.
Trunk this VLAN towards the 7750.

Enable OSPF/ISIS or static routing to be able to route between the systems.

If static;
7750 * this is based on SROS14. If using 13 or older, syntax will differ:

configure
router "Base"
static-route-entry "192.168.50.0/24"
-------------------------------------------------------------------------------
*A:SR03>config>router>static-route-entry$ info
----------------------------------------------
next-hop 192.168.60.2
no shutdown
exit
----------------------------------------------

Modify your policies to import this new static route to your core IGP.

OS6850:

ip static-route 0.0.0.0/0 gateway 192.168.60.1

On the VPLS service, create a sap towards the 6850 with the designated VLAN ID to be used on the 6850.
Tag the VPLS VLAN on 6850 on trunk port, and either make a trunk or access port in this VLAN to extend the VPLS service via ordinary VLAN switching via 6850.
