network redundancy, protocols for redundancy

Network Redundancy Protocols Redundancy is a common point for today’s topologies. Especially in mission-critical networks it is not acceptible that using only one gateway to reach a point. Because one gateway means single point of failure. With multiple gateways, you can still reach the remote node even if the gateway that you connect fails. As […]

vlan(virtual local area network) port assignment

VLAN Port Assignment VLANs can be assigned statically and dynamically. Static configuration is more common, but dynamic is also used. Static VLAN assignment is like its name. You will statically assign the ports to the VLAN. Dynamic VLAN assignment can be done by VLAN Membership Policy Server(VMPS). VMPS needs VLAN-MAC address relationship database. Here, we […]

vlan(virtual local area network)

VLANs (Virtual Local Area Networks) VLANs(Virtual Local Area Networks) are the virtual networks that you can seperate big networks into smaller networks. This can be done for reducing broadcast traffic, network performance improvement, security purpose or to seperate different departments each other and for network flexibility. Basically VLAN (Virtual Local Area Network) VLANs are logical […]

Traffic Flow without ECMP, alcatel-lucent service routers, SR 7750

ECMP (Equal Cost Multi Path) If the total IGP cost to a destination are same for two path, these paths are called Equal Cost Multi Path. Normally if there are two path that have same IGP cost, in Alcatel-Lucent Service Routers, lower interface wins and the traffic goes through it. Traffic Flow Without ECMP Think […]

LDP configuration example topology, alcatel-lucent service routers, SR 7750

LDP Configuration on Alcatel-Lucent Service Routers To do an LDP configuration example, we will use the below basic topology. Here, we will configure these two routers to become an LDP peer and establish an LSP session. LDP Configuration Example Topology Configuration on Router A A:RouterA>config>router # interface “to_RouterB” address port 1/1/1 exit interface “system” […]
