All routers on this network have been configured with P1M-SM and R1 is the rendezvous point However, when asymmetric routing is implemented to modify link usage the network begins to drop certain multicast traffic Which action corrects the problem?
Place the routes affected by asymmetric routing in a VRF.
Remove the asymmetric routing and use spanning tree to manage link usage.
Add a static Mroute for routes that are failing.
Configure the routers to use PIM-DM instead of PIM-SM.
Refer to the exhibit.
An engineer applied the configuration on R1 to prevent network 192.168.1.0/24 from being propagated outside of area 5. After the change, users have reported they are not able to access any of the application servers that were working before. While checking the routing table of the peer router. The engineer notices R1 stopped propagating any routes outside are 5. Which action must be taken to fix the problem?
Configure an additional filter-list on R1 for inbound traffic to allow external router into area 5.
Reconfigure the filter-list statement to apply in the inbound direction
Change the prefix-list action to permit and add an explicit deny statement for network 192.168.1.0/24
Add a permit statement for 0.0.0.0/0 le 32 to the end of the prefix-list 10 override the implicit deny.
What is the role of segment routing mapping server?
It advertises a local SID mapping policy to all the mapping clients.
It works with IGP instances to calculate the prefix-SIDs in the absence of a mapping policy.
It selects multiple mapping entries to create overlapping active mapping policies.
It reads and translates remotely received SIDs from other mapping servers to create SID mapping entries.
Which difference should be considered when intradomain or interdomain multicast routing is implemented?
Interdomain multicast routing requires an IS-IS or OSPF neighbor relationship between the domains but intradomain multicast routing requires only BGP
Interdomain multicast routing relies on PIM-DM and intradomain multicast routing relies on PIMSM.
interdomain multicast routing uses BIDR-PIM to establish neighbor relationships between AS and interdomain multicast routing uses MSDP
A network uses intradomain multicast routing without interdomain routing but networks that use interdomain multicast routing must also apply intradomain routing
Refer to the exhibit.
Routers RA and RB are IS-IS peers configured for NSF but router RC is an IS-IS peer without NSF capability If RA undergoes processor switchover what is the effect on the network environment?
If RC is operating without the Cisco configuration option all three routers tear down their peering relationships and re-establish peering
All peer relationships remain up and the link-state database is unchanged
All peer relationships remain up, but the link-state database is rebuilt on each device
If RC is operating without the Cisco configuration option only 2 routers tear down their peering relationships and re-establish peering
Refer to the exhibit.
An engineer applied the summarization configuration on R1 for four networks (192.168.20.0/24 to 192.168.23.0/24) in area 1 and eight networks (192.168.32.0/24 to 192.168.39.0/24) in area 2 to stop the flooding of all the customer routes.
While checking the routing table of R2, the engineer noticed that R1 is still sending only specific routes to R2. Which configuration should the engineer apply on R1 to summarize routes?
Option A
Option B
Option C
Option D
Refer to the exhibit.
Traffic flow from router R1 to router R6 is delay-sensitive It must consider potential link-failure and node-failure conditions Which configuration must an engineer apply to router R1 to route traffic to router R6 if router R2 fails?
Option A
Option B
Option C
Option D
An engineer is troubleshooting slow performance issues on a customer’s network after the last multicast configuration change was applied on it While checking the running configuration on the router the engineer notices there are many ip igmp join-group commands applied on several interfaces of the router which caused the high CPU utilization usage. What action must the engineer take to solve this issue?
Configure ip igmp static-group command on all interfaces
Remove ip igmp join-group command on all unnecessary interfaces
Configure all router interfaces to be process-switched by increasing the query interval
Remove unnecessary members from the IGMP group
Refer to me exhibit.
A network engineer sets up a multihoming eBGP topology where multiple Autonomous Systems connect to ASN 64501. The engineer wants to block all the routers coming from ASN 64502. but allow all the others. For that purpose, the following AS Pam prefix 1st s being used:
What must be fixed to achieve this result?
The AS-PATH filter must be defined inside the route-map mode
At the end ip as-path access-list 10 permit .* must be included
The statement must be modified with ip as-path access-list 1 deny _64502_
The statement must CM modified with ip as path access list 1 deny A64502$
Refer to the exhibit.
A network engineer applied configuration on R1 to summarize all ISIS routes, but R2 Is still receiving specific routes from R1. The engineer has confirmed that both routers are configured with the correct summarization configuration, but R1 is not sending the correct summary routes. Which configuration must be applied to router R1 to summarize routes within Level 1?
Option A
Option B
Option C
Option D
