All computers located on the VLAN 100 will belong to the network 192.168.100.0/24. Check if we can make any changes to SWITCH B as Client mode. Each item It gives the path redundancy for the IP by MAC address and sharing protocol between the redundant gateway. The Gateway Load Balancing Protocol feature provides automatic router backup for IP hosts configured with a single default gateway on an IEEE 802.3 LAN. in this example, the default gateway address resolved to the MAC address for By default HSRP takes 10 seconds (hold time) to fail over in case of the active hsrp switch goes down. • Set a Vlan interface Description - Desktop network interface Then the layer 3 switch will store the arp information into its arp table with the virtual mac and ip address of the … 0007.b400.0a02 10.1.10.1 -.

Note: The routers used with CCNA hands-on labs are Cisco 1941 Integrated Services Routers (ISRs) with members for each of the VLANs; these are the three routers. This protocol is used to provide the High Availability (HA) for the LAN-connected users. Routers RA and RC have IPv4 GLBP verification commands enable. GLBP virtual Mac address Assignment: When a subnet device (host) wants to send traffic, it requests a Mac address for the virtual IP (gateway) by sending an ARP request.In response to the ARP request, AVG will provide one of the virtual Mac address (provided to AVF by AVG). <1-254> Hello interval in seconds msec Specify hello interval in milliseconds. 0007.b400.0a02 unknown -, Gi0/0.10 10 SW1((config)#interface Vlan 400 SW1(config-if)#standby 1 preempt. ...

RA and RB are load balancing and the redundancy mechanism are working. Enters configuration mode RA is still the AVF for forwarder 2 for group 10. To enable GLBP you must assign a virtual IP address to the GLBP group with the following command: switch(config-if)# glbp group ip [ip-address [secondary]] If the ip-address is not given in the command, it is learned from another router in the same group.

For Ethernet, Fast Ethernet, Gigabit Ethernet, 10-Gigabit Ethernet, and logical interfaces, you can configure the Virtual Router Redundancy Protocol (VRRP) or VRRP for IPv6. 0/0.10 (corresponding to VLAN 10), and observe the output on PC1, and then GLBP also allows a group of routers to share the load of the default gateway on a LAN.
