Is it possible?
I want to achieve Qos and RTP compression
I have Point-Point conncetiond
One side is MetroEthernet - VLAN
One side is G.SHDSL - ATM - BVI
Thanks

No, you can have RTP compression only on serial point-to-point normally routed links.

Thank you,
Do you have a example config for qos
One side is MetroEthernet
One side is Atm and BVI

Configure route-bridged encapsultation under a p.t.p. subif for atm.
Nothing else should be necessary.

For Metro site no problem
But For G.SHDSL I cannot apply service-policy giving th following
Router(config-if-atm-vc)#interface BVI1
Router(config-if)# bandwidth 256
Router(config-if)# ip address 1.1.2.2 255.255.255.252
Router(config-if)#service-policy output WAN-EDGE
Class Based Weighted Fair Queueing not supported on interface BVI1
Router(config-if)#
Here is my G.SHDSL Config;
class-map match-any Call-Signaling
match ip dscp cs3
match ip dscp af31
class-map match-all Voice
match ip dscp ef
!

Do not use BVI. Use "atm route-bridged" under subif as recommended above.

Thank you,
You said RTP is not possible;
But router doesnt out any error?

Check with show commands, no compression is occurring, as one end of media is Ethernet.
It might be possible with PPPoE, but I haven't personally ever seen that.

For the Metro Ethernet site
I have Catalyst 3560
I have point-point links (128k-512k)
What do you recommend?
Thanks

Install normally first and observe. Once working, some testing can be made. But you will need a true router on both sides.
