Exam 350-401 topic 1 question 435 discussion

Correct answer is B: https://www.cisco.com/c/en/us/td/docs/ios/12_2s/feature/guide/fs_bgivt.html

B is correct

B is the answer The referencing object under vrf configuration mode should be the route-map not the ACL

The answer is B. Pay attention to the name of route-map and ACL

I think it really depends on the router's software For example, Router1, I got this: R1(config-vrf)#import ipv4 unicast ? <1-2147483647> Upper limit on import prefixes without hogging memory map Route-map based VRF import R1(config-vrf)#import ipv4 unicast In Router2, I got this: ip vrf customer-a address-family ipv4 import route-map export-to-vrf exit-address-family

Correct answer I B:

Correct answer is B:

Answer: B R-1(config-vrf)#import ipv4 ? multicast Import prefixes from IPv4 Multicast table unicast Import prefixes from IPv4 Unicast table R-1(config-vrf)#import ipv4 un R-1(config-vrf)#import ipv4 unicast ? <1-2147483647> Upper limit on import prefixes without hogging memory map Route-map based VRF import SW-1(config-vrf)#import ipv4 unicast ma R-1(config-vrf)#import ipv4 unicast map

Correct answer is B

Correct Answer B: Tested in LAB. Need to do a few more things to get the leaking working. Like running VRF Lite with BGP and distributing the routes to BGP. https://www.cisco.com/c/en/us/support/docs/ip/ip-routing/200158-Configure-Route-Leaking-between-Global-a.html (this article uses a STD ACL, but EXTENDED ACL also works with destination set to Any, like in the Answer B) A: reference to wrong ACL, ACL also has source/dest reversed. C: import statement has route-map. should be just 'map'. D: import statement is missing the 'map' keyword.

C. is technically (syntax) correct but I did not see route leaking in the lab, probably IOL restricyions: ! ip vrf cust_1 rd 11:11 import ipv4 unicast map cust_2_to_cust_1 ! route-map cust_2_to_cust_1 permit 10 match ip address cust_2_netw ! ip access-list extended cust_2_netw permit ip 172.16.1.0 0.0.0.255 any ! cisco_R3(config)#do s ip ro vrf cust_1 | b Ga Gateway of last resort is not set 192.168.1.0/24 is variably subnetted, 3 subnets, 2 masks C 192.168.1.0/24 is directly connected, Ethernet0/0.20 L 192.168.1.1/32 is directly connected, Ethernet0/0.20 L 192.168.1.200/32 is directly connected, Ethernet0/0.20 cisco_R3(config)# cisco_R3(config)#do s ip ro vrf cust_2 | b Ga Gateway of last resort is not set 172.16.0.0/16 is variably subnetted, 2 subnets, 2 masks C 172.16.1.0/24 is directly connected, Ethernet0/0.30 L 172.16.1.1/32 is directly connected, Ethernet0/0.30 S 192.168.1.0/24 [1/0] via 192.168.1.1 cisco_R3(config)#

1. enable 2. configure terminal 3. ip vrf vrf-name 4. rd route-distinguisher 5. import ipv4 unicast | multicast [prefix-limit] map route-map 6. exit 7. route-map map-tag [permit | deny] [sequence-number] etc..... Its "B"

B is correct, The key word is using unicast map instead of route-map

C can't be right ecause in route map is defined name of ACL, I would vote B

answer is B

Agree the answer is B
