all intermediary nodes. If Fully Protect Path is checked on the Circuit Routing Preferences panel, you
must:
Add two spans for all path protection or unprotected portions of the circuit route from the source to
•
the destination
Add one span for all BLSR or 1+1 portions of route from the source to the destination
•
Suppose you want to create a fully protected circuit from a path protection node subtended from the
BLSR. For example, a BLSR is comprised of Node 1, Node 2, and Node 3, and a path protection subtends
from Node 3 to Node 4. To create a circuit from Node 4 to Node 1, you include two spans in the circuit
route from Node 4 to Node 3, since both the working and protect path must be provisioned for the path
protection portion of the circuit, and you provision one circuit span from Node 3 to Node 1, since the
BLSR provides protection.
