IS-IS Traffic Engineering (TE) is an extension of IS-IS to support MPLS TE. As specified in RFC 5305 and RFC 4205, IS-IS TE defines new TLVsand sub-TLVs in IS-IS LSPs to carry TE information, floods LSPs to implement the flooding and synchronization of TE information, and transmits TE information to the CSPF module. IS-IS TE supports MPLS …

implementing load balancing through IS-IS: Networking Requirements As shown in Figure 1: CX- A, CX- B, CX- C, and CX- D run IS-IS to implement interconnection in the IP network. CX- A, CX- B, CX- C, and CX- D are Level-2 routers in area 10. Load balancing is required to transmit the traffic of CX- A to CX- D through CX- B and CX- C. Figure 1 Networking diagram of configuring IS-IS load balancing Device Interface IP Address Device …

OSPF supports virtual link …
Continue reading Comparing IS-IS and OSPFHow you can deploy ISIS on IPRAN ? I will talk about two way that can help you to deploy ISIS on IPRAN , the first one if you have a small network that not containing a lot of routers , in this case you can make all the routers as Level 2 ISIS the …
Continue reading ISIS on IPRANIS-IS was initially designed by the ISO and is used as a routing protocol based on CLNP addressing. CLNP is a Layer 3 protocol in the OSI reference model posed by the ISO. Figure 1 OSI reference model OSI uses systemized (or hierarchical) addressing. The services at the transport layer in OSI can be addressed …
