MCT for VLL
This feature supports dual-homing connectivity of CE devices to PE devices. Dual-homing enables
link level and node level redundancy for CE's connected to PE's.
Figure 184 is a typical topology with MCT end-points for VLL. The VLL end-point connections from a
single CE are dual homed to two PE nodes acting as an MCT cluster. From the CE, it has a LAG
connection between CE and PE and is unaware of the MCT.
• PE1 and PE2 are two nodes of MCT cluster and work like a single PE. Similarly PE3 & PE4 are
MCT cluster.
• CE1 is connected to PE1 and PE2 through a LAG.
• CE2 is connected to PE3 and PE2 through a LAG.
• PE1 has PW1 and PW3 vll PWs for same instance connected to remote MCT pairs.
• PE2 has PW2 and PW4 vll PWs for same instance connected to remote MCT pairs.
• For MCT pair PE1,PE2 PE1 is selected as active for a VLL instance, which it specifies as
Active(A) in pw-redundancy status TLV during PW connection setup to remote PE pair.
• For MCT pair PE3 and PE4 nodes, PE4 is selected as active, which it specifies as Active(A) in
pw-redundancy status TLV during PW connection setup to remote PE pair.
