Inerconnect 6850 routers for vlan traffic

[saravanan_01]

Hello Team,

Iam using Alcatel OS 86850 switch with below version level.

Welcome to the Alcatel OmniSwitch 6000
Software Version 6.1.3.719.R01 GA, December 06, 2006.


I have configured the 6850 - router 1 with 4 VLAN with Ip forwarding.

> show ip interface
Total 5 interfaces
Name IP Address Subnet Mask Status Forward Device
--------------------+---------------+---------------+------+-------+--------
Loopback 127.0.0.1 255.0.0.0 UP NO Loopback
vlan60 192.168.20.1 255.255.255.224 UP YES vlan 60
vlan70 192.168.20.33 255.255.255.224 UP YES vlan 70
vlan80 192.168.20.65 255.255.255.224 UP YES vlan 80
vlan90 192.168.20.97 255.255.255.224 UP YES vlan 90


I have configured the 6850 - router 2 with 4 VLAN with Ip forwarding.

> show ip interface
Total 5 interfaces
Name IP Address Subnet Mask Status Forward Device
--------------------+---------------+---------------+------+-------+--------
Loopback 127.0.0.1 255.0.0.0 UP NO Loopback
vlan10 192.168.30.1 255.255.255.224 UP YES vlan 10
vlan20 192.168.30.33 255.255.255.224 UP YES vlan 20
vlan30 192.168.30.65 255.255.255.224 UP YES vlan 30
vlan40 192.168.30.97 255.255.255.224 UP YES vlan 40

Now I have a challenge of connecting a client pc from Vlan 10 and Vlan 90
How can I establish this

What are the steps to be done to establish the above connection and also where to coneect the physical
connection needed between the Router 1 and Router 2

kind regards,
Saravanan

Hi
You will connect one PC to VLAN 10 an 90 at the same Time?

I have two client pc
The First Pc in Vlan 10--> Switch --> Router 1 and the second pc in the Vlan 90 --> Switch --> Router 2
Both the Router 1 and Router 2 is not interconnected as of now.

I need the steps to configure the interconnection between two routers .

Hi
The tow router are conneced to the same Switch. Can you create a drawing with the Routers und Switches.

1. Add a link between switches
2. create a Transfer net on the link between both routers.
3. give each router an IP on that link
4. Do a static route entry for the "other nets" pointing to the "other" Routers IP on transfer net.

(You could also extend the vlans to the other switch by tagging them to the link and provide an IP the the other router in each vlan)


Next time: use full class C nets.. waaaaay nicer to read.

Hello Team,

Since one of L3 switch failed Iam trying to replace with other 6850 Switch.

Now I have problem in interconnecting between the L3 Switches.
I have configured as per

vlan 2 enable name InterconnectVLAN
vlan 2 802.1q 1/48
ip interface interconnectVLAN address 192.168.20.129 mask 255.255.255.224 vlan 2
ip static-route 192.168.30.0 mask 255.255.255.224 gateway 192.168.20.130 metric 1
ip static-route 192.168.30.32 mask 255.255.255.224 gateway 192.168.20.130 metric 1
ip static-route 192.168.30.64 mask 255.255.255.224 gateway 192.168.20.130 metric 1
ip static-route 192.168.30.96 mask 255.255.255.224 gateway 192.168.20.130 metric 1


Switch on the right side (192.168.30.X)

vlan 2 enable name InterconnectVLAN
vlan 2 802.1q 1/48
ip interface interconnectVLAN address 192.168.20.130 mask 255.255.255.224 vlan 2
ip static-route 192.168.20.0 mask 255.255.255.224 gateway 192.168.20.129 metric 1
ip static-route 192.168.20.32 mask 255.255.255.224 gateway 192.168.20.129 metric 1
ip static-route 192.168.20.64 mask 255.255.255.224 gateway 192.168.20.129 metric 1
ip static-route 192.168.20.96 mask 255.255.255.224 gateway 192.168.20.129 metric 1

Both the switches are connected in the port 48 .
Now 192.168.20.129 is able to reach 192.168.20.130 vice versa
but the IP subnets in other vlan are not reachable.

Iam trying to ping 192.168.20.1 from 192.168.20.129 second L3 switch. But is not reacahble

kindly help me to sort out the issue.
regards
Saravanan

Please provide complete (relevant) configs.
It should work.
please post ipconfig /all of the PC (must have proper default gateway)
Please show routing table and ensure the the interfaces are up
show ip-static route
show ip interface

in general:
Have the switch be default gateway in the vlans of each network.
Have the clients configured their (VLAN)defaut gateway.
Have the interconnected switches with proper routes.. (Static, dynamic ...)
