Issue:
We have 2 sites connected to a PBX at the main site per IPSec Site-to-Site VPN.
Paging works through multicast packages, but they do not pass through the vpn. The phones are connected via the VPN from the other site.
How do I set up routers so that they can display phones on the VPN?
Solution:
The usual IPSec Site-to-Site tunnel can not do this.
The VTI interface can transmit multicast traffic in a VPN tunnel. (VIT interface must use site-to-site VPN)
(1) Select "VPN Tunnel Interface" for the VPN connection
(2) Go to Configuration> Network> Interface> VTI> click on Add VTI interface.
It has support for IGMP (multicast) function.
