A. The “network 2.0.0.0” BGP configuration command is missing on R2 and the “network 3.0.0.0” BGP configuration command is missing on R3.
B. R2 and R3 are not using the loopback0 IP address as the source address for the BGP messages to each other.
C. The “neighbor 2.2.2.2 ibgp-multihop 2” BGP configuration command is missing on R3 and the “neighbor 3.3.3.3 ibgp-multihop 2” BGP configuration command is missing on R2.
D. The “No Sync” BGP configuration command is missing.

What is the maximum number of parallel routes that can be injected into the routing table when using the iBGP multipath load sharing feature?
A. The number of parallel paths injected into the routing table will depend on the IGP currently in use within the iBGP domain.
B. iBGP multipath can support up to 4 parallel paths.
C. None, multipath is supported on eBGP only when used in conjunction with the update-source command.
D. iBGP multipath can support up to 6 parallel paths.
E. The maximum number of parallel paths injected into the routing table is specified by BGP MED and ranges from 2 to 256 parallel paths.
Answer: D

What does the following command accomplish?
sanjose#clear ip bgp 10.1.1.1 in prefix-filter
A. The sanjose router will perform an outbound soft reconfig to the 10.1.1.1 neighbor.
B. The 10.1.1.1 router will perform an inbound soft reconfig on the updates from the sanjose neighbor.
C. The sanjose router will send out the ORF prefix-list so that a new route refresh will be received from the 10.1.1.1 neighbor.
D. The bgp session between the sanjose and the 10.1.1.1 router will be reset so that all the new bgp updates from the sanjose router can be processed by the inbound prefix-list at the 10.1.1.1
router.
E. The 10.1.1.1 router will send out the ORF prefix-list so that a new route refresh will be received from the sanjose neighbor.
F. The bgp session between the sanjose and the 10.1.1.1 router will be reset so that all the new bgp updates from the 10.1.1.1 router can be processed by the inbound prefix-list at the sanjose router.
