Consider the network in Figure. Suppose AS3 and AS2 are running OSPF for their intra-AS routing protocol. Suppose AS1 and AS4 are RIPing for your intra-AS routing protocol. Suppose eBGP and iBGP are used for the intra-AS routing protocol. Initially, assume that there is no physical link between AS2 and AS4. By which protocols do routers 1c, 1d, 3a, and 3c know about the network prefix x?

which protocols do routers 1c, 1d, 3a, and 3c know about the network prefix x?
The answers to choose from are -1a,1b -none -1b,1c -all -1a,1b,1c -1b,1c -1b,1c,1d -1a,1b,1c,1d 19) Consider the network shown below. Suppose AS3 and AS2 are running OSPF for their intra-AS (10pts) routing protocol. Suppose AS1 and AS4 are running RIP for their intra-AS routing protocol. Suppose eBGP and iBGP are used for the inter-AS routing protocol. Initially suppose there is no physical link between AS2 and AS4. a) Which routers in AS1 run eBGP? b) Which routers in AS1 run...
. Consider the network shown below. Suppose AS3 and AS2 are running RIP for their intra-AS routing protocol. Suppose AS1 and AS4 are running OSPF for their intra-AS routing protocol. Suppose eBGP and BGP are used for the inter-AS routing protocol. Initially suppose there is no physical link between AS2 and AS4. 2c a. Router 4c learns about prefix x from which routing protocol: OSPF, RIP, eBse or iBR? b. Router 3b learns about x from which routing protocol? c....
Q1 Error detection/correction Can these schemes correct bit errors: Internet checksums, two-dimendional parity, cyclic redundancy check (CRC) A. Yes, No, No B. No, Yes, Yes c. No, Yes, No D. No, No, Yes E. Ho, hum, ha Q2 CRC vs Internet checksums Which of these is not true? A. CRC's are commonly used at the link layer B. CRC's can detect any bit error of up to r bits with an r-bit EDC. c. CRC's are more resilient to bursty...
