Ccna routing and Switching Complete Study Guide

telnet 2001:db8:3c4d:1:a14c:8c33:2d1:be3d

Trying 2001:db8:3c4d:1:a14c:8c33:2d1:be3d... Open

 

Server1>

Okay, great—but that was way too much effort! Let’s create an entry into the hosts table 

of R1 so we don’t have to type an IPv6 address when trying to access that host.

R1(config)#

ipv6 host Server1 2001:db8:3c4d:1:a14c:8c33:2d1:be3d

R1(config)#

do sh host

[output cut]

 

Host Port Flags Age Type Address(es)

Server1 None (perm, OK) 0 IPV6 2001:DB8:3C4D:1:A14C:8C33:2D1:BE3D

 

Now we can just type this from now on (the name is case sensitive).

R1#

telnet Server1

Trying 2001:DB8:3C4D:1:A14C:8C33:2D1:BE3D... Open

 

Server1>

Or better yet, just the name (Telnet is the default).

R1#

Server1

Trying 2001:DB8:3C4D:1:A14C:8C33:2D1:BE3D... Open

 

Server1>

exit

 

Also, ping using the name.

R1#

ping Server1

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 2001:DB8:3C4D:1:A14C:8C33:2D1:BE3D, timeout is 

2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 0/0/1 ms

Step 2: Create an ACL on R2 that stops Telnet to the remote host Server1 (2001:db8

:3c4d:1:a14c:8c33:2d1:be3d). The name is absolutely case sensitive when applying to an 

interface.
