Consider the network shown below. Suppose AS1 and AS2 are running OSPF for their intra-AS routing protocol. • Suppose AS3 and AS4 are running RIP for their intra-AS routing protocol. • Suppose eBGP and iBGP are used for the inter-AS routing protocol. • Network X is attached to Router 1d in AS1. 4b 4c 4a AS4 3c 2c 3b 3a 1c 1b 1/2 2a 2b Y 1a AS3 AS2 > 1d X AS1 For each router listed in the left column, identify the routing protocol or path length at the right column. Router 2a learns network X by Router 3b learns network X by Router 1b learns network X by Router 4c learns network X by Router 4b learns network X by Router 1d learns about network Y (attached to Router 3b in AS3) via router 1c. What is the AS-PATH length for this route to network Y? Now assume AS1 uses Hot Potato Routing as its iBGP, and all links have equal cost. What is the AS-PATH length from Router 1d to Network Y?
