[cisco-voip] no QoS solution in WAN with L2VPN over FR!!!

[Djokic Sinisa]

hi group..

 

 

 

according to TAC engineer who talked with colleague of mine cisco doesn't
have solution for next scenario..

 

 

in my country TELCO offers L2VPN over frame-relay network as well as over
ethernet..

 

 

so, according to cisco we cannot offer QoS solution for those customers who
still use FR as access to L2VPN..

 

 

so the issue is in branch office WAN router..

 

the problem occurs since we need to create interface BVI on every branch
router and assign ip address to it instead of frame-relay serial
subinterface..

this is a MUST, beacuse of frame-relay encapsulation on the FR access, and
central office understands only ethernet frames..

this way we're bounding FR to eth..

 

so, we cannot apply LLQ or CBWFQ or GTS to interface BVI, it's not
supported..

 

 

also, when we appy it to frame-relay subinterface ( which has all the
configuration like classic FR interface except the fact that belongs to
bridge-group and hasn't  ip address ), it doesn't work..

 

any thoughts how to overcome this..

 

although i'm not shure it can be helped..

 

 

thanx..

 

 

regards..
