I have inter vlan routing configured on my switch. The switch is directly connected to the router. On the router I have static routes to the switch, the static routes point to the management vlan. My question is should I have each static route point the vlan interfaces or to the management vlan, in which case is vlan 1 in my config. Which method is better or correct? any performance differences? Or either one is correct? Thanks for the assistance!!!
here is the config
the port between switch and router is a physical port, " no switchport"
router ethernet 1/0
ip address 172.21.19.1 255.255.255.0
switch with inter-vlan routing
vlan 1 172.21.19.0 255.255.255.0 mangement
vlan 23 172.23.0.0 255.255.0.0
vlan 20 172.20.0.0 255.255.0.0

Hi
There are probably 2 ways to approach this
1) Create a dedicated vlan for the router to switch connection and use a /30 eg.
router
eth1/0
ip address 192.168.5.1 255.255.255.252
int vlan 3
ip address 192.168.5.2 255.255.255.252
and then put the port that the router connects to in vlan 3. Then your routes are
ip route 172.23.0.0 255.255.255.0 192.168.5.2
ip route 172.23.0.0 255.255.0.0 192.168.5.2
ip route 172.20.0.0 255.255.0.0 192.168.5.2
or
2) Pretty much the same as above except instead of using a dedicated vlan make the port that the router connects to a L3 routed port ie. on the switch
int fa0/10
no switchport
ip address 192.168.5.2 255.255.255.252
And then add routes as in 1
You can of course run a routing protocol between the L3 switch and the router.
As for the options i would go with option 2 if possible.

Hi Bart,
I removed my message, as I can see Jon already answered.
