I have a 3745 router that connects to remote branches via point to point T1s. I want to replace P2P with 10/100 Ethernet. 2 FE ports on board are being used. I want to add a NM-16ESW module to provide additional Ethernet connections.
My question is "can I configure each port on the NM-16ESW module as a routed port so that I can connect each remote site to the FE port on the switch module?" The way I read, I should be able to do this using SVI. Can anyone confirm this?
Thanks Paresh. One additional question. I am assuming that when I do this I need to add vlan subnets in my routing protocol. For example, let's say the vlan100 is in 172.100.x.x network and I use rip routing protocol. So I should have
With newer IOS;es, you necessarily dont need to create vlans and then assign vlans to the ports and assign ip addresses to the vlan interfaces to get layer 3 routing on each port. You can do a "no switchport" directly under the fast E ports of the module and this command configures the switch port as a Layer 3 port. Take a look at this FAQ
[toc:faq]The ProblemOn traditional switches whenever we have a trunk
interface we use the VLAN tag to demultiplex the VLANs. The switch needs
to determine which MAC Address table to look in for a forwarding
decision. To do this we require the switch to do...
