Hello,
I have two C4506 switches and I would like to create two L3 links between them by using only one physical link.
I will then assign each L3 link to a different VRF.
I think I have two choices but I'm not sure however that the second one is possible...
Does someone have an idea about this?
---------------
1st choice: creating two VLANs and two SVIs on each switch
interface Vlan10
ip address 10.10.10.1 255.255.255.252
ip vrf forwarding vrf1
interface Vlan20
ip address 10.10.10.5 255.255.255..252
ip vrf forwarding vrf2
interface GigabitEthernet0/0
switchport mode trunk
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 10,20
2nd choice: using dot1q subinterfaces
interface GigabitEthernet0/0
no switchport
interface GigabitEthernet0/0.10
encapsulation dot1q 10
ip address 10.10.10.1 255.255.255.252
ip vrf forwarding vrf1
interface GigabitEthernet0/0.20
encapsulation dot1q 20
ip address 10.10.10.5 255.255.255.252
ip vrf forwarding vrf2
