What is routed VPLS?
Routed VPLS (R-VPLS) allows a VPLS instance to be associated with an IES or VPRN interface. Hosts within the same subnet communicate directly with each other without the need for a router, but any communication with a host that is external to the subnet requires routing.
What is nokia VPLS?
Nokia’s VPLS service provides a bridged or switched Ethernet Layer 2 network. Equipment connected to SAPs forward Ethernet packets into the VPLS service. The 7450 ESS, 7750 SR, or 7950 XRS participating in the service learns where the customer MAC addresses reside, on ingress SAPs or ingress SDPs.
What is bridge domain in VPLS?
VPLS is a multipoint Layer 2 VPN technology that connects two or more customer devices using bridging techniques. A bridge domain, which is the building block for multipoint bridging, is present on each of the PE routers. The access connections to the bridge domain on a PE router are called attachment circuits.
What are bridge domains?
A bridge domain is a set of logical ports that share the same flooding or broadcast characteristics. Like a virtual LAN (VLAN), a bridge domain spans one or more ports of multiple devices. You can also group one or more bridge domains within a single instance, or virtual switch.
What is bridge domain in Cisco?
Bridge domain interface is a logical interface that allows bidirectional flow of traffic between a Layer 2 bridged network and a Layer 3 routed network traffic. Bridge domain interfaces are identified by the same index as the bridge domain. Only one bridge domain interface can be associated with a bridge domain.
How does Cisco VPLS work?
Virtual Private LAN Services (VPLS) is a class of VPN that supports the connection of multiple sites in a single bridged domain over a managed IP/MPLS network. VPLS uses edge routers that can learn, bridge and replicate on a VPN basis.
Why do we need bridge domain?
A bridge domain is a set of logical ports that share the same flooding or broadcast characteristics. Like a virtual LAN (VLAN), a bridge domain spans one or more ports of multiple devices. IRB enables you to route packets to another routed interface or to another bridge domain that has a Layer 3 protocol configured.
