Refer to the exhibit.
The OSPF routing protocol is redistributed into the BGP routing protocol, but not all the OSPF routes are distributed into BGP.
Which action resolves the issue?
- A . Include the word external in the redistribute command
- B . Use a route-map command to redistribute OSPF external routes defined in an access list
- C . Include the word internal external in the redistribute command
- D . Use a route-map command to redistribute OSPF external routes defined in a prefix list.
C
Explanation:
If you configure the redistribution of OSPF into BGP without keywords, only OSPF intra-area and inter-area routes are redistributed into BGP, by default. You can use the internal keyword along with the redistribute command under router bgp to redistribute OSPF intra- and inter-area routes.
Use the external keyword along with the redistribute command under router bgp to redistribute OSPF external routes into BGP.
-> In order to redistribute all OSPF routes into BGP, we must use both internal and external keywords. The full command would be (suppose we are using OSPF 1): redistribute ospf 1 match internal external
Note: The configuration shows match internal external 1 external 2. This is normal because OSPF automatically appends “external 1 external 2” in the configuration. In other words, keyword external = external 1 external 2. External 1 = O E1 and External 2 = O E2.

In which circumstance does the BGP neighbor remain in the idle condition?

An engineer configured Reverse Path Forwarding on an interface and noticed that the routes are dropped when a route lookup fails on that interface for a prefix that is available in the routing table.
Which interface configuration resolves the issue?
- A . ip verify unicast source reachable-via rx
- B . ip verify unicast source reachable-via any
- C . ip verify unicast source reachable-via allow-default
- D . ip verify unicast source reachable-via 12-src
B
Explanation:
According to this question, uRPF is running in strict mode because packets are dropped even when that route exists in the routing table. Maybe packets are dropped because the receiving interface is different from the interface the local router uses to send packets to that destination. The ip verify unicast source reachable-via rx command enables Unicast RPF in strict mode.
To enable loose mode, administrators can use the any option (ip verify unicast source reachable-via any). In loose mode, it doesn’t matter if we use this interface to reach the source or not.
The allow-default option allows the use of the default route in the source verification process.
