P Router Configuration
We need static routes on P routers for rx pindown on S-PE, i.e. to force PWs destined to a specific address to
be transported over certain links.

S-PE Configuration
At S-PE we have 2 PW-HE interfaces (1 for each PW) and each uses a different interface list for tx pin-down
(has to match the static config at P routers for rx pin-down). Each PW-HE has its PW going to A-PE (pw-id
has to match what's at A-PE).
