VPLS Exceptions on J-Series and SRX-series devices
The VPLS implementation on a J-series or SRX-series device is
similar to VPLS implementations on M-series, T-series, and MX-series
routers, with the following exceptions:
J-series or SRX-series devices do not support aggregated
Ethernet interfaces. Therefore, aggregated Ethernet interfaces between
CE devices and PE routers are not supported for VPLS routing instances
on J-series or SRX-series devices.
VPLS routing instances on J-series or SRX-series devices
use BGP to send signals to other PE routers. LDP signaling is not
supported.
VPLS multihoming, which allows connecting a CE device
to multiple PE routers to provide redundant connectivity, is not supported
on J-series or SRX-series devices.
J-series or SRX-series devices do not support BGP mesh
groups.
J-series or SRX-series devices only support the following
encapsulation types on VPLS interfaces that face CE devices: extended
VLAN VPLS, Ethernet VPLS, and VLAN VPLS. Ethernet VPLS over ATM LLC
encapsulation is not supported.
Virtual ports are generated dynamically on a Tunnel Services
PIC on some Juniper Networks routing platforms. J-series or SRX-series
devices do not support Tunnel Services modules or virtual ports.
The VPLS implementation on J-series or SRX-series devices
does not support dual-tagged frames. Therefore, VLAN rewrite operations
are not supported on dual-tagged frames. VLAN rewrite operations such
as pop-pop, pop-swap, push-push, swap-push, and swap-swap, which are
supported on M-series and T-series routing platforms, are not supported
on J-series or SRX-series devices.
