Hi,
Not sure if this is at all possible, but...
- Does CUBE HA / HSRP support the use of Layer 3 port channel on the CUBE router end?
We are looking to make use of Nexus vPC capability by doing CUBE Layer 3 Portchannel > Nexus 7k Layer 2 vPC in access mode.
[this is to account for individual link and core switch failure, without forcing CUBE failover]
The HA documentation looks like it uses one link only per HSRP group.
Cheers,
Rob

Hi Rob,
I didn't find anything saying that you can't use Port-Channel for CUBE HA.
Do you have any problem in the configuration?
Hope this helps.

Hi
see this post in another thread.

Someone was able to do this on a 3800 series ISR after a bit of messing about.

have you done this ? I would like to do layer 3 port channel on my CUBE which is connected in the VSS.

I have 2 cubes and i am planning for
during interface configuration i am planning to give.
I will be leaving the service provider IP in the interfaced 0/0 and leave the customer IPs on 0/1 then add 0/2 for the heartbeat which will be VIP. I’ll remove all of the loopbacks.
Is it necessary to give the singnalling and media IP address from the provider on the CUBE itself or is there any way i can do it.
Please let me know your suggestion. i am stuck with the configuration from 70 days.
Also is there any other scenario which i can make sure the service provider will failover the calls once the Primary router is out of service.

Hi,
Your VIP address is not attached to any physical interface, its configured as part of HSRP. Your physical interface are part of the HSRP group. For HSRP, you do not need a dedicated interface for heart beat. This is only required if you are using redundacy groups on the ISR4k or ASR
The only IP you configure is the signalling IP of your provider. This will typically be configured in your dial-peers

can we configure active active for outgoing calls with 2 sip trunks and ask service provider to send calls to the CUBE 1 always and if it is not reachable it can send to CUBE 2 from service provider side.
In that scenario do we need to add the media and signalling IP address on the CUBE itself please suggest on it. Also the session target was shared by service provider which is another network which does not have anything to do with the singnalling and media ip network, so do we need to add the singalling and media IP address on the same CUBE , if that is the case in both cubes i will put this SIG AND MEDIA IP as Loopback address , Kindly suggest.

I am not sure what is not clear, please explain. HSRP is not used on the ISR4K. You need to use redundancy group. It is similar but different from HSRP. You need three interfaces for this as shown in the document I sent to you.
1. You need an interface to connect to your internal network
2. You need an interface that connects to your ITSP
3. You need a dedicated interface for heartbeat. This is used for check-pointing signalling and media on both CUBES
Your two VIP will be configured on the two interfaces. Ie one VIP for the internal network and another for the external network that connects to your ITSP.
