Pseudowire Grouping
PWHE Interfaces
The virtual circuit (VC) types supported for the PW are types 4, 5 and 11. The PWHE acts as broadcast
interface with VC types 4 (VLAN tagged) and 5 (Ethernet port/Raw), whereas with VC type 11 (IP
Interworking), the PWHE acts as a point-to-point interface.
Pseudowire Grouping
When pseudowires (PWs) are established, each PW is assigned a group ID that is common for all PWs created
on the same physical port. When a physical port becomes non-functional or disabled, Automatic Protection
Switching (APS) signals the peer router to get activated and L2VPN sends a single message to advertise the
status change of all PWs that have the Group ID associated with the physical port. A single L2VPN signal
thus avoids a lot of processing and loss in reactivity.
Pseudowire grouping is disabled by default.
