L2 TUNNEL

Hello!

I have a problem with changing hardware from CISCO to Mikrotik.
I need to create a L2 tunnel for SIP traffic exchange from ISP to own Debian server, which has an IP address from /30 subnet.
Previously we had a CISCO for it and all worked fine.

How it worked on Debian:

We made a bridge

		brctl addbr br0
		ip addr add 10.12.10.234/30 dev br0
		ip link set br0 up promisc on

And made a L2tp interface

                ip l2tp add tunnel remote 214.214.214.2 local 125.125.125.125 tunnel_id 200 peer_tunnel_id 200 encap ip
		ip l2tp add session tunnel_id 200 session_id 103 peer_session_id 301 l2spec_type none
		ip link set dev l2tpeth0 up

After it we add it to bridge

brctl addif br0 l2tpeth0

How it worked on CISCO:

pseudowire-class twc
		 encapsulation l2tpv3
		 interworking ethernet
		 protocol none
		 ip local interface FastEthernet0/0

		interface FastEthernet0/0
		 ip address 214.214.214.2 255.255.255.252
		 ip access-group IPFILTER in
		 duplex auto
		 speed auto

		interface FastEthernet0/1
		 no ip address
		 duplex auto
		 speed auto
		 no keepalive
		 xconnect 125.125.125.125 100 encapsulation l2tpv3 manual pw-class twc
		  l2tp id 301 103
		 !

Thank you in advance

I did not understand: in this way you have replaced debian with cisco or have you made a bridge between them?
Thanks in advance of the answer
