First Hop Redudancy for IPv6 can be achieved via different protocols like HSRP, GLBP or VRRP. The Gateway Load Balancing Protocol (GLBP) feature provides automatic router backup for IPv6 hosts configured with a single default gateway on an IEEE 802.3 LAN. GLBP provides benefits of Load Sharing, Multiple Virtual Routers, Preemption and Authentication.

Understaing of First Hop Redudancy Routinng Protocols
In this document, Gateway Load Balancing Protocol (GLBP) is configured on the LAN interface (FastEthernet 0/0) of Router R3 and R4. These two routers are advertised with a IPv6 network of 1111:11:11:11::11/64 by ISP-Router. As both the routers have reachability to ISP-Router, they are acting as a gateway to reach ISP network and providing redundancy.
The virtual IPv6 address used is FE80::260:3EFF:FE11:6770 by command glbp 11 ipv6 FE80::260:3EFF:FE11:6770. Router R2 acting as a host is configured with a default static route pointing toward the Virtual IPv6 Address. The command is ipv6 route ::/0 FastEthernet0/0 FE80::260:3EFF:FE11:6770.
I am configuring an SG-350 from scratch. Upon login using factory credentials, I go to create a vlan as I am looking to segment ny switch with two vlans. I want to have 2 vlans: 1) one port on a management vlan and 2) the remainder of the ports on another...
Hi, I have a Cisco ASR 9010 Router and I want to configure BGP BlackHole.I want to know about the syntax that is needed to be applied in order to do this, because I am having some issues regarding BH application in IOS XR.Lets say that I want to appl...
I have a Cisco C2960 in production which was compromised. The switch has been pulled and I'm trying to determine if the IOS image was tampered with. Since the switch is End-of-Life / End-of-Support, I'm unable to get from Cisco what the hash is to va...
Hello, We have Cisco 2960X with two etherchannels (2 ports each). One is static (mode on) to ESXi host and other active to another switch. On ESXi host load balancing policy is set to src-dst-ip (called IP hash) and it works as I see traffic on both ...
1)May I know the difference of ISIS metric-type internal and external while redistributing ? 2)I have configured metric-type external alone without metric keyword while redistributing but it is not effecting. May I know the reason why does not I...
