BT static routing to CPE
by Tom Ammon 01 May '20

01 May '20

Hi All, I've inherited a circuit that can't be replaced, on which I need to get some services working, from BT in the UK. The sales people are saying that they can't give me an additional PA IPv4 block (static routed behind the CPE->PE link), that the only option for expanding the addressing is to increase the size of the subnet on the link. Does anyone here know better, and if so, could you point me to someone at BT who could help get an additional PA block allocated for us?

Howdy,, How do we contact the nanog mail admins? I looked at https://archive.nanog.org/list and https://archive.nanog.org/list/faq but apparently someone thought it'd be clever to redact all the email addresses from that page. "Questions should be directed to[email protected]." Thanks, Bill Herrin -- William Herrin bill(a)herrin.us https://bill.herrin.us/
