Thank you!! I wasn't creating the subif between ASBRs.. guess thought the routes would get through with vpnv4 and vpnv6.. learning more each time.. Thank you for your content.. more detailed and in depth than most and good segmentation.
Hi Rob , between ASBR on sub interface can we use encapsulation dot1q 1 or other then vlan 1 , because in my lab main interface is part of VRF but when i create sub interface of main interface with encapsulation dot1Q with vlan 1 , the sub interface is up between ASBR but main interface goes down??? can you please help me to sort out
The main interface is VLAN 1, any sub interface you create is NOT VLAN 1. G0/1.2 could be VLAN 2 or 200 or 61, it really doesn't matter. In your case, for each VRF, you need to create a separate dot1q subinterface. VRF 101 g0/1.101 encap dot1q 101 ip add 101.0.0.1/30 VRF 102 g0/1.102 encap dot1q 102 ip add 102.0.0.1/30 And so on.
The encapsulation needs to be a different VLAN ID. In my lab, each link is it's own broadcast domain, so it doesn't matter, I can reuse the same VLAN IDs everywhere and it doesn't bother anything. If you're using OVAs in vSphere attached to the same vSwitch, then unique VLAN IDs are needed.

VRF 101
g0/1.101
encap dot1q 101
ip add 101.0.0.1/30
VRF 102
g0/1.102
encap dot1q 102
ip add 102.0.0.1/30
And so on.
do we need to keep different encapsulation vlan for sub interfaces or it can be same ????

Hi, rob,great video as usual! Can you make a video for vrf leacking?
Yes I can
21:09 on the vrf C1 RT import should be 1:11, right?
It sure looks like it, seems like I typod.
