Inter VLAN Routing

Inter VLAN Routing

Hello,

The situation I have is as follows, I have X2 WWAN links between the same branch office, one active and one redundant. I don’t want to use STP as the recovery is too slow, and will thus affect VOIP if calls are active. I want to create X3 VLAN’s as follows:-


Switch1 2626

VLAN01 192.168.0.0 (Connected to Radio01)
VLAN02 197.99.99.0 (Connected to LAN)
VLAN03 192.168.1.0 (Connected to Radio02)


Switch2 2626


VLAN01 192.168.0.0 (Connected to Radio01)
VLAN02 197.99.97.0 (Connected to LAN)
VLAN03 192.168.1.0 (Connected to Radio02)

From what I’ve read, inter VLAN routing is automatically enabled between VLAN’s, however I want to manually control this instead of the switch automatically adding the entry. I don’t know this is possible, I come from a 10 year Cisco base…

Switch01 (routing entry added to VLAN03)

ip route 197.99.97.0 255.255.255.0 VLAN01 1
ip route 197.99.97.0 255.255.255.0 VLAN03 50

Switch02 (routing entry added to VLAN03)

ip route 197.99.99.0 255.255.255.0 VLAN01 1
ip route 197.99.99.0 255.255.255.0 VLAN03 50

Can this be done on this switch instead of using a router?

Thank you in advance!

Re: Inter VLAN Routing

Hi,

You won't be able to set administrative distances on the 2600's.

With STP, if using RSTP (802.1w) it should only take a couple of seconds to recover in the event of a link failure.

What you could also consider would be to use MSTP (802.1s) to make use of the redundant WAN link - data traffic on one, voice traffic on the other.
