BT HH5A bridge modem + router: move BT > Sky...?

[pseud]

Folks,
1/ I’m in the UK
2/ I’ve been using BT happily for about 4-5 years & now swapping to Sky/ Now (cheaper)
3/ My set up is OpenWRT/ BT HH5A as a bridge ‘modem’ with router (OpenWRT) behind it
4/ I’ve taken the modem set-up from the most excellent guide on the HH5A by @bill888’s, and:

BT Homehub 5A with NowTV fibre

NowTV is exactly the same as Sky, was with them last year. You get a Sky IP address and they support IPv6. They actually use DHCP Client Protocol and support two methods for authentication, DHCP ClientID works with all connections and according to a Sky employee, IPv6 with Prefix Delegation on about 80% of connections. On my line I can use either method, hence I've previously stated that ClientID can be omitted, which in fact is not true of all lines and requires IPv6 with PD enabled, so you ma…

All the above assumes one device and so I’m interpreting the above across two devices, which is why I thought to post a wee query.

From the above I figure bridge /etc/config/network should be okay - perhaps the option ds_snr_offset '0' and option macaddr '02:yy:yy:yy:yy:yy' should be removed?

But, router /etc/config/network should - perhaps - be changed so:

config interface 'wan'
option device 'eth1'
option proto 'dhcp'
option clientid '77616E4D414364647265737340736B7964736C7C7769666970776F7264414243444546' # optional, being hex of wanMACddress@skydsl|wifipwordABCDEF
option macaddr 'wanMACddress' # optional
option ipv6 '1'
option metric '10'
option peerdns '0'
list dns '1.1.1.1'
list dns '1.0.0.1'

config interface 'wan6'
option device '@wan'
option proto 'dhcpv6'
option reqaddress 'try'
option reqprefix '56'
option norelease '1'
option disabled '0'
option metric '10'

I’m left unsure where option ifname 'dsl0.101' should go, if anywhere - there’s already list ports 'dsl0.101' in the bridge and it doesn’t seem to make sense in the router.

Any tips of best set up are welcome!
