A friend of mine recently asked me to assist them with configuring a Cisco ISR router for BT Infinity / Fibre. I decided to share the configuration for others to leverage.
Please note this configuration is far from complete and represents a real bare bones configuration without additional security and device hardening present. It is not in anyway a recommended configuration but can be used as a test / baseline.
Router: 2900 (2911)
IOS: 15.1(4)M4
ADSL card:
NAME: "ADSL/VDSL over POTS supporting ADSL1, ADSL2, ADSL2+ and VDSL2 on Slot 0 SubSlot 1", DESCR: "ADSL/VDSL over POTS supporting ADSL1, ADSL2, ADSL2+ and VDSL2"
PID: EHWIC-VA-DSL-A
