SVI on 7600 Router

[bmoorewiz]

Guys, Can someone tell me the benefit of doing SVI's on a 7600 router, or any router, instead of L3 interfaces? Especially when you are already doing OSPF?

I hope this helps.

Austin thanks, good read on packet life. However, that is the opposite of what I asked :) 

That is the benefit of the routed interface, I want the benefit of the SVI interface as I will be recommending a routed interface and I am trying to plays devils advocate so I am prepared.

packetlife.net mentioned - the SVI is more flexible - therefore you configure the physical interface as trunk for Transport of several VLANs - but you need per SVI one subnet-adress to make it work.

One possible benefit of using an SVI, you can have another port in the VLAN, ready to patch over to if the primary/active port or its line card fails.

This can reduce downtime for such failures.

Especially handy when the port that fails is the only remote access port to device.

Also, you can talk most anyone into re-patching cable from one port to another.
