IPv6 is enabled in the infrastructure to support customers with an IPv6 network over WAN and to connect the head office to branch offices in the local network. One of the customers is already running IPv6 and wants to enable IPv6 over the DMVPN network infrastructure between the headend and branch sites.
Which configuration command must be applied to establish an mGRE IPv6 tunnel neighborship?
- A . tunnel protection mode ipv6
- B . ipv6 unicast-routing
- C . ipv6 nhrp holdtime 30
- D . tunnel mode gre multipoint ipv6
D
Explanation:
The command “tunnel mode gre multipoint ipv ” sets the encapsulation mode of the tunnel to mGRE IPv6.
An engineer creates a default static route on a router with a hop of 10.1.1.1. On inspection, the engineer finds the router has two VRFs, Red and Blue. The next hop is valid for both VRFs and exists in each assigned VRF.
Which configuration achieves connectivity?
- A . ip route vrf BLUE 0.0.0.0 255.255.255.255 10.1.1.1
ip route vrf RED 0.0.0.0 255.255.255.255 10.1.1.1 - B . ip route vrf Red 0.0.0.0 0.0.0.0 10.1.1.1
ip route vrf Blue 0.0.0.0 0.0.0.0 10.1.1.1 - C . ip route vrf 0.0.0.0 0.0.0.0 10.1.1.1
- D . ip route vrf Red 0.0.0.0 255.255.255.255 10.1.1.1
ip route vrf Blue 0.0.0.0 255.255.255.255 10.1.1.1
Refer to the exhibit.
A customer reported an issue with a fiber link failure between RC and RE Users connected through the spoke location face disconnection and packet drops with the primary email server (172.16.16.1) but have no issues with the backup email server (172.16.26.1). All the router loopback IPs are advertised through the OSPF protocol.
Which configuration resolves the issue?
- A . Option A
- B . Option B
- C . Option C
- D . Option D
SIMULATION
A DMVPN network is preconfigured with tunnel 0 IP address 192.168.1.254 on the HUB, IP connectivity, crypto policies, profiles, and EIGRP AS 100. The NHRP password is ccnp123, and the network ID and tunnel key is EIGRP ASN Do not introduce a static route.
Configure DMVPN connectivity between routers BR1 and BR2 to the HUB router using physical interface as the tunnel source to achieve these goals:
ON BR2
