I've just changed from ADSL where the config was working perfectly. I've still got to re-add my remote and P2P vpn config and EIGRP configs back in but can't as i can't even get this right :-(
Your help is much needed and appreciated (in advance)
Thanks

I'm going through the differences now betwen your config and mine to decipher what the difference is. But in the meant time, whatever the difference, it's WORKING

hello
glad to hear its working.
The two things i could see was:
1) the main eth0 interface was shutdown
2) your ppp authentication

BT Infinity supports RFC4638 (MTU greater than 1492 over PPPoE) so you may not require these lines:
ip mtu 1492
ip tcp adjust-mss 1452
I have successfully configured both a Cisco 867VAE and a 1921/EHWIC-VA-DSL with a default MTU of 1500 on BT Infinity so it may also work on the 887VA.

BT do support RFC4638 however you need to configure your side to negotiate a bigger MRU. You can then remove the 'ip mtu 1492' and 'ip tcp adjust-mss 1452' commands:
interface Ethernet0
mtu 1508
no ip address
!
interface Ethernet0.101
encapsulation dot1Q 101
ip virtual-reassembly in
pppoe enable group global
pppoe-client dial-pool-number 1
pppoe-client ppp-max-payload 1500
