Hi group,
Got a something that I don't fully understand, hope someone can help me out.
I've got a VLAN with the address range (10.10.10.x) configured on a Layer 3 switch. The switch is doing all the inter-vlan routing and it works great however when I want to publish the connected networks via Rip V2 to the rest of the network I run into issues.
I'm trying to publish the connected routes out a interface on vlan 1 that has the following ip address 192.168.1.x/22. No rip packets are sent to the Vlan 1 network.
Example config snippet:
ip classless ! interface vlan 10 ip address 10.10.10.x 255.255.255.0 ! interface vlan 1 ip address 192.168.1.x 255.255.255.252 ! router rip Version 2 redistribute-connected network 192.168.1.0 !
However as soon as I change the subnet mask to 24 bits or add the following line to the Vlan 1 interface it works: ip address 192.168.1.xx 255.255.255.0 secondary
This is the part I don't understand, why is Rip being sent out a interface with a 24 bit subnet mask and not a 22. I would have thought the ip classless command would have enabled this to work.
A bit stumped on this one, hope someone can enlighten me.
Thanks in advance.
