PC-1> ipconfig /release

PC-1> ipconfig /renew

PC-1> ipconfig /all

ISP# show ip dhcp binding

ISP# show ip dhcp server statistics

2. Конфигуриране на DHCPv6:

a) конфигуриране на SLAAC

Router-1(config) # ipv6 unicast-routing

Router-1(config) # interface G 0/0

Router-1(config-if) # ipv6 address 2001:db8:acad:a::1/64

Router-1(config-if) # ipv6 address fe80::1 link-local

Router-1(config-if) # no shutdown

Router-1 # show ipv6 interface G 0/0

Switch-1(config) # sdm prefer dual-ipv4-and-ipv6 default

Switch-1 # reload

Switch-1(config) # interface vlan 1

Switch-1(config-if) # ipv6 address autoconfig

Switch-1 # show ipv6 interface

PC-1> ipconfig /all

б) конфигуриране на Stateless and DHCPv6

Router-1(config) # ipv6 dhcp pool IPV6POOL-A

Router-1(config-dhcpv6) # domain-name STATELESS-DHCP.net

Router-1(config-dhcpv6) # dns-server 2001:db8:acad:a::abcd

Router-1(config) # interface G 0/0

Router-1(config-if) # ipv6 nd other-config-flag

Router-1(config-if) # ipv6 dhcp server IPV6POOL-A

Router-1 # show ipv6 interface G 0/0

PC-1> ipconfig /all

PC-1> ipconfig /release6

PC-1> ipconfig /renew6

Router-1 # show ipv6 dhcp binding

Router-1 # show ipv6 dhcp pool

в) конфигуриране на Stateful DHCPv6

Router-1(config) # ipv6 dhcp pool IPV6POOL-A

Router-1(config-dhcpv6) # address prefix 2001:db8:acad:a::/64

Router-1(config-dhcpv6) # no domain-name STATELESS-DHCP.net

Router-1(config-dhcpv6) # domain-name SATEFULL-DHCP.net

Router-1 # show ipv6 dhcp pool

Router-1 # debug ipv6 dhcp detail

Router-1(config) # interface G 0/0

Router-1(config-if) # shutdown

Router-1(config-if) # ipv6 nd managed-config-flag

Router-1(config-if) # ipv6 nd prefix default no-autoconfig

Router-1(config-if) # ipv6 dhcp server IPV6POOL-A

Router-1(config-if) # no shutdown

Router-1 # show ipv6 interface G 0/0

PC-1> ipconfig /all

PC-1> ipconfig /release6

PC-1> ipconfig /renew6

Router-1 # show ipv6 dhcp binding

Router-1 # show ipv6 dhcp pool

г) конфигуриране на DHCPv6 Relay:

Router-2(config) # interface G 0/0

Router-2(config-if) # ipv6 nd managed-config-flag

Router-2(config-if) # ipv6 dhcp relay destination 2001:db8:acad:1::1 S 0/0

3. Конфигуриране на Hot Standby Router Protocol (HSRP) и Gateway Load Balancing Protocol (GLBP):

        

а) Конфигуриране на HSRP:

Router-1(config) # interface G 0/0

Router-1(config-if) # standby 1 ip 192.168.1.254

Router-1(config-if) # standby 1 priority 150

Router-1(config-if) # standby 1 preempt

Router-2(config) # interface G 0/0

Router-2(config-if) # standby 1 ip 192.168.1.254

Router-1 # show standby

Router-2 # show standby

Router-1 # show standby brief

Router-2 # show standby brief

PC-1> ping 10.10.10.10 -t /Loopback на Router-3/

Прекъсва се връзката между Switch-1 и Router-1 и се наблюдава превключването на трафика през другия Gateway.

б) Конфигуриране на GLBP:

Router-1(config) # interface G 0/0

Router-1(config-if) # no standby 1

Router-1(config-if) # glbp 1 ip 192.168.1.254

Router-1(config-if) # glbp 1 priority 150

Router-1(config-if) # glbp 1 preempt

Router-1(config-if) # glbp 1 load-balancing round-robin

Router-2(config) # interface G 0/0

Router-2(config-if) # no standby 1

Router-2(config-if)# glbp 1 ip 192.168.1.254

Router-2(config-if) # glbp 1 load-balancing round-robin

Router-1 # show glbp brief

Router-2 # show glbp brief

PC-1> ping 10.10.10.10 -t

PC-1> arp –a /кой е MAC адреса за 192.168.1.254 ?/

Да се натовари с още трафик и отново да се изпълни:

PC-1> arp –d *

PC-1> arp –a /има ли промяна на MAC адреса за 192.168.1.254 ?/
