Question # 25

Refer to the exhibit. The network administrator has configured the Customer Edge router (AS 64511) to send only summarized routes toward ISP-1 (AS 100) and ISP-2 (AS 200).

router bgp 64511

network 172.16.20.0 mask 255.255.255.0

network 172.16.21.0 mask 255.255.255.0

Refer to exhibit.

Question # 29

Routing protocols are mutually redistributed on R3 and R1. Users report intermittent connectivity to services hosted on the 10.1.1.0/24 prefix. Significant routing update changes are noticed on R3 when the show ip route profile

command is run. How must the services be stabilized?

Options:

The issue with using BGP must be resolved by using another protocol and redistributing it into EIGRP on R3

The routing loop must be fixed by reducing the admin distance of iBGP from 200 to 100 on R3

The routing loop must be fixed by reducing the admin distance of OSPF from 110 to 80 on R3

The issue with using iBGP must be fixed by running eBGP between R3 and R4
