BGP Auto FRR

mammoura — Wed, 20 Apr 2016 21:04:55 +0000

As a protection measure against faults over links, BGP Auto Fast Reroute (FRR) is applicable to networks with primary and backup links. With BGP Auto FRR, traffic can be switched between two BGP peers or next hops within sub-seconds. With BGP Auto FRR, if a peer has multiple routes with the same prefix that are …

Principles of Traffic Policing

mammoura — Thu, 14 Jan 2016 22:24:08 +0000

Process of Traffic Policing In traffic policing, the Committed Access Rate (CAR) is used to control traffic. Packets are first classified according to pre-defined matching rules. Packets that conform to the specified rate limit are forwarded directly, whereas packets that exceed the specified rate limit are dropped or have their priorities re-marked before being retransmitted. …

Example for Configuring Inter-AS Seamless MPLS+HVPN

mammoura — Tue, 29 Dec 2015 08:32:54 +0000

In the inter-AS seamless MPLS+HVPN networking, an HVPN connection between a CSG and AGG is established, and an inter-AS seamless MPLS LSP between an AGG and MASG is established. The inter-AS seamless MPLS+HVPN networking obtains the collective advantages of the inter-AS seamless MPLS network and HVPN. Networking Requirements In Figure 1, the access and aggregation layers …

BGP Route Reflector ” RR”

mammoura — Sun, 06 Sep 2015 12:50:32 +0000

Fully meshed connections need to be established between IBGP peers to ensure the connectivity between IBGP peers. If there are n CX devices in an AS, n x (n-1)/2 IBGP connections need to be established. When there are a lot of IBGP peers, network resources and CPU resources are greatly consumed. Route reflection can solve the …

OSPF Fast Convergence

mammoura — Sat, 08 Aug 2015 23:06:54 +0000

OSPF fast convergence is an extended feature of OSPF implemented to speed up the convergence of routes. It includes the following: I-SPF Incremental SPF (I-SPF) recalculates only the routes of the changed nodes rather than all the nodes when the network topology changes. This speeds up the calculation of routes. PRC Partial Route Calculation (PRC) …

Hierarchy Of VPN – HoVPN

mammoura — Tue, 28 Apr 2015 11:59:57 +0000

Hierarchy Of VPN – HoVPN Hierarchical Model and Plane Model On a BGP/MPLS IP VPN, as the key devices, PEs perform the following functions: PEs ensure the access for users, and thus require a great number of interfaces. PEs manage and advertise VPN routes, and process user packets. Thus, the PEs require large-capacity memory and …

Configure a CCC Local Connection

mammoura — Sat, 25 Apr 2015 23:24:44 +0000

A local CCC connection refers to the connection between two local CEs, that is, two CEs connected to the same PE. Similar to a Layer 2 switch, the PE can switch traffic without the need to set up a static LSP. Networking Requirements Figure 1 shows the CE is connected with the PE through a POS …

Basic Principles of VPLS

mammoura — Wed, 15 Apr 2015 20:27:29 +0000

VPLS is an L2VPN technology based on MPLS and Ethernet technologies. VPLS can provide the multipoint-to-multipoint VPN services, which is better than the earlier point-to-point L2VPN services, and L3VPN services requiring carriers to manage the routing information. In the drafts relevant to VPLS, two VPLS network architectures are proposed: VPLS with PWs logically fully meshed …
