[Spce-user] Virtual Network Interface as RTP Interface and missing v6gateway

[Hohl Matthias]

Hello,

 

in my test environment I want following setup:

 

I want 2 network interfaces in the same subnet for ipv4 and ipv6.

 

So I created 1 main interface eth0 and 1 alias interface (virtual interface)
eth0:1

On eth0 the subscriber should connect and on eth0:1 the peering should
connect (inbound and outbound)

 

My Problem:

If I create a second network interface like eth1 instead of eth0:1 I have a
problem with routing, cause same IP addresses are in the same subnet, so I
have to create the alias eth0:1.

eth0:1 for rtp_engine works, but if I generate the config ngcp created an
additional eth0 RTP_Interface:

 

                     rtp_interface eth0:1_peering=eth0:1_peering is sync
between config and db

                     rtp_interface eth0=eth0 is sync between config and db

                     rtp_interface ext=ext is sync between config and db

 

is this a bug? Normally eth0 is the "ext" interface, so there is no need to
generate eth0 as rtp_interface separately.

 

Anyway it works, and if I set rtp_interface "eth0:1_peering" in my peering
settings and my outbound socket, I can place calls over eth0:1

I just want to be sure, that my config is the right way to deal with virtual
network interfaces in the same subnet 

 

 

BTW: 

I also found out, that I can't set a v6gateway in network.yml in mr6.5.3 for
ipv6 connectivity. 

I have to add this manually in the etc/network/interfaces but this is not
ngcpapply stable.

Without that, I can't ping it the interfaces via ipv6.

 

 

 

My network.yml looks like this:
