Layer 3 Port-Channel with a Layer 2 Subinterface - ASR1001-x to 6807 VSS

[nw-team01]

I have a curious Problem.

I have a ASR1001-x that i wan't to redundantly connect to a VSS pair on 6807's. So use a Port-channel, right? So far so good.

Config from Router:

interface Port-channel1

ip address 10.160.1.106 255.255.255.252

 

interface Port-channel1.980

encapsulation dot1Q 980

ip address 10.160.1.98 255.255.255.248

interface TenGigabitEthernet0/0/0

no ip address

channel-group 1 mode active

interface TenGigabitEthernet0/0/1

no ip address

channel-group 1 mode active

Config from VSS:

interface Port-channel240

no switchport

ip address 10.160.1.105 255.255.255.252

 

interface Port-channel240.980

encapsulation dot1Q 980

ip address 10.160.1.99 255.255.255.248

 

interface Vlan980

ip address 10.160.1.97 255.255.255.248 -> this is for testing only

 

interface TenGigabitEthernet1/1/30

no switchport

no ip address

channel-group 240 mode passive

 

interface TenGigabitEthernet2/1/30

no switchport

no ip address

channel-group 240 mode passive

Remotely L2 connected to vlan 980 the other ASR1001-x

ip address 10.160.1.100 255.255.255.248

From VSS ping to 10.160.1.106 and 10.160.1.98 is successful.

From the ASR ping to 10.160.1.105 and 10.160.1.99 is sucessfull. ping to 10.160.1.97 and 10.160.1.98 is unsuccessful.

From the other remotly connected via L2 on vlan 980:

ping to 10.160.1.97 is successful. ping to 10.160.1.98 is successful.

So what i have is that the ASR and the VSS can only communicate Point-to-Point but not across an L2 connection or a SVI.

Any help is appreciated.
