143.116.123.0/24
A dynamic routing protocol is configured and worked well on all the routers shown in the figure. A new network 143.116.123.0/24 was added to Re and advertised in its routing table 60s ago. Which of the following are true?
a. if using RIP, router a, b, c, d, e should display the new network in their routing table.
b. if using RIP, all of the router should display the new network in their routing table.
c. if using IGRP, router a, b, c, d, e should display the new network in their routing table.
d. if using IGRP, only router e should display the new network in their routing table.
e. if using OSPF, all of the router should display the new network in their routing table.
f. if using OSPF, router b, c, e should display the new network in their routing table.
ans: a, d, e
my question is about d. Doesn't IGRP support triggered update?? why only e? I thought all the routers should have the new route in the routing tables.
Anyone can help?
TIA!!! |
