![]() On each router we mention an index value which is carried in the IGP advertisement and the receiving end calculates the label based on index value it has received from the node.It is done on the basis of SRGB (segment routing global block) defined on the router, for example if the SRGB defined on the router is 16000 to 23999 which is also the default SRGB and router receives 5 as index value then the label would be 16005.There are two important components in SR, Prefix-SID and Adjacency SID, with the help of these two we can reach anywhere in the network.As we are using links state routing protocols, we can use IGP FRR in segment routing. ![]() Now the intermediate nodes just have to remove(pop) the labels belonging to them and steer the packet to the node where the next label belongs to.
