// This script exercises global routing code in a mixed point-to-point
// and csma/cd environment
//
// Network topology
//
// n0
// \ p-p
// \ (shared csma/cd)
// n2 -------------------------n3
// / | |
// / p-p n4 n5 ---------- n6
// n1 p-p
// | |
// ----------------------------------------
// p-p
//
// - at time 1 CBR/UDP flow from n1 to n6's IP address on the n5/n6 link
// - at time 10, start similar flow from n1 to n6's address on the n1/n6 link
//
// Order of events
// At pre-simulation time, configure global routes. Shortest path from
// n1 to n6 is via the direct point-to-point link
// At time 1s, start CBR traffic flow from n1 to n6
// At time 2s, set the n1 point-to-point interface to down. Packets
// will start to be dropped
// At time 3s, call RecomputeRoutingTables() and traffic will
// start flowing again on the alternate path
// At time 4s, re-enable the n1/n6 interface to up. Will not change routing
// At time 5s, call RecomputeRoutingTables() and traffic will start flowing
// again on the original path
// At time 6s, set the n6-n1 point-to-point Ipv4 interface to down (note, this
// keeps the point-to-point link "up" from n1's perspective). Packets
// will traverse the link and be dropped at n6 upon receipt. These drops
// are not visible in the pcap trace but in the ascii trace.
// At time 7s, call RecomputeRoutingTables() and traffic will flow again
// through the path n1-n2-n5-n6
// At time 8s, bring the interface back up.
// At time 9s, call RecomputeRoutingTables() and traffic will flow again
// through the path n1-n6
// At time 10s, stop the first flow.
// At time 11s, start a new flow, but to n6's other IP address (the one
// on the n1/n6 p2p link)
// At time 12s, bring the n1 interface down between n1 and n6. Packets
// will start to be dropped
// At time 13s, call RecomputeRoutingTables() and traffic will
// start flowing again on the alternate path
// At time 14s, re-enable the n1/n6 interface to up. This will change
// routing back to n1-n6 since the interface up notification will cause
// a new local interface route, at higher priority than global routing
// At time 15s, call RecomputeRoutingTables(), but there is no effect
// since global routing is lower in priority than static routing
// At time 16s, stop the second flow.
