•
The size of the TFTP boot packets are 1400 bytes. All the MPLS-LDP links must support the transmission

Configuring Intermediate L2 Cloud
Configure the following to enable ICLs in the Cluster setup to be available across the L2 network:
•
Two ASR 9000 routers that run MPLS LDP across the central link (2 10 GE links).
•
ICL connected to routers on 1G ports that are configured as L2 interfaces.
•
XConnect to direct all the ICL traffic from the 1G ports on the L2 interfaces to the MPLS/LDP link,
thereby creating a pseudo wire for each ICL link.
