I saw in a book, it says to configure an IPv6 address in a serial interface, it has given the following command:
(config)#interface serial 0/0
(config-if)#ipv6 address 2001:ae32:cb8:231c::/64 eui-64
My doubt is , how the router is going to take its interface's MAC address for this, because there is no MAC address in the serial interface?
Some clarification on this would be highly appreciated.
Thanks in advance!
Here is a configuration for ipv6. Notice that the MAC address of the fa0/0 interface is in the eui-64 address of the ser1/2 interface.
R1#sh int fa0/0
FastEthernet0/0 is down, line protocol is down
Hardware is DEC21140, address is ca00.0cf8.0000 (bia ca00.0cf8.0000)
MTU 1500 bytes, BW 100000 Kbit, DLY 100 usec,
reliability 255/255, txload 1/255, rxload 1/255
R1(config-if)#ipv6 address 2001:ae32:cb8:231c::/64 eui-64
R1(config-if)#do sh ipv6 int ser1/2
Serial1/2 is up, line protocol is down
IPv6 is enabled, link-local address is FE80::C800:CFF:FEF8:0 [TEN]
Global unicast address(es):
2001:AE32:CB8:231C:C800:CFF:FEF8:0, subnet is 2001:AE32:CB8:231C::/64 [EUI/T
Joined group address(es):
MTU is 1500 bytes
ICMP error messages limited to one every 100 milliseconds
ICMP redirects are enabled
ND DAD is enabled, number of DAD attempts: 1
ND reachable time is 30000 milliseconds
Hosts use stateless autoconfig for addresses.
