Refer to the exhibit.

R3 is:
Which command must the engineer implement to resolve the issue?
A R3# ip msdp sa-filter in 192.168.3.1
B. R3# no ip msap sa-filter in 192.168.1.1
C R3# no ip msdp peer 192.168.1.1
D. R3# ip msdp sa-filter out 192.168.1.1
The engineering team at ISP_1 must improve network stability time and minimize the impact of routing instabilities from other domains to unicast transit services in the backbone R1 is part of an OSPF- enabled network, and acts as an ASBR connected via interface GiO/1 to the external domain The OSPF exponential backoff algorithm RFC 3623 with helper mode is already implemented on R1 Which additional configuration must the ISP_1 team apply to suppress routing instability for 3 minutes'?
Refer to the exhibit.

CE1 is the gateway router into the provider network via PE1. A network operator must
inject a default route into OSPF area 0. All devices inside area 0 must be able to reach PE1. Which configuration achieves this goal?




Refer to the exhibit. Multicast traffic destined from T1 and T2 routers to RP routers works well. A network engineer observes problems with multicast traffic flows between Site-A and Site-B. Site-A users fail to receive multicast stream on Site-B via RPTY site, while Site-B users fail to receive multicast stream on Site-Avia RPTZ site. Which action must be implemented to resolve the issues?
What is the difference between a source tree and a shared tree in a multicast environment?
After changing the IP address on an IOS XR router, an engineer cannot ping the new address Which step did the engineer forget to complete?

Refer to the exhibit. HostB receives an IPTV traffic stream from the multicast source at 192.168 10.1. When router RB is powered down, it impacts multicast traffic forwarding to downstream peers. The RA and RB routers reside in the same physical location. Which two configurations must be implemented so that HostB receives the multicast stream even when RB is powered down? (Choose two )
What Is a characteristic of a segment routing mapping server?
Refer to the exhibit.

P1 and PE3 Cisco IOS XR routers are directly connected and have this configuration
applied. The BGP session is not coming up. Assume that there is no IP reachability problem and both routers
can open tcp port 179 to each other. Which two actions fix the issue? (Choose two.)
