Thank you but it does not mater - it was a bug related to dialer
interface - thank you Mark for pointing that one.
When we are using pppoe between the ASBRs the ASBR that is the pppoe
client does not populate the cef table with the labels from the ASBR
that is the pppoe server.
If i change the config to pure ethernet it works ok.
br,
Ovidiu
