QoS Support for VPLS SAPs and IP interface in a Routed VPLS service

The following lists the support available for routing protocols on IP interfaces bound to a VPLS

A routed VPLS context supports all spanning tree and port-based split horizon capabilities that a

non-routed VPLS service supports.

SAP ingress classification (IPv4 and MAC criteria) is supported for SAPs configured in

the service. SAP ingress policies cannot be associated with IES IP interface.

Egress Port based queuing and shaping are available. It is shared among all the SAPs on

Port based Egress Marking is supported for both routed packets and bridged packets. The

existing access egress QoS policy can be used for Dot1p marking.

IES IP interface bound to routed VPLS services, IES IP interface on access SAPs and IES

IP interface on Access-Uplink SAPs are designed for use with inband management of the

node. Consequently, they share a common set of queues for CPU bound management

traffic. All CPU bound traffic is policed to pre-defined rates before being queued into

CPU queues for application processing. The system uses meters per application or a set of

applications. It does not allocate meters per IP interface. The possibility of CPU

overloading has been reduced by use of these mechanisms. Users must use appropriate

security policies either on the node or in the network to ensure that this does not happen.

Static-routing is supported

BGP is not supported

OSPF is not supported

ISIS is not supported

BFD is not supported

VRRP is not supported

ARP is supported

DHCP Relay is not supported
