When the active router in a VRRP group fails, which router assumes the role and forwards packets?
When the active router in a VRRP group fails, which router assumes the role and forwards packets?
In a Virtual Router Redundancy Protocol (VRRP) group, when the active router (also known as the master router) fails, the router designated as the backup router assumes the role of the active router and begins forwarding packets. This backup router has been configured to take over should the master router become unavailable, ensuring continued high availability and reliability of the network. Therefore, the correct term for the router that assumes the role when the active router fails is 'backup'.
HSRP usese Active/Standby VRRP usese Master/Backup these roles are for the routers in the virtual group
On Vol. 2 p260 of the Official Certification Guide, Wendell says that VRRP uses an active/standby, NOT master/backup redundancy approach.
VRRP uses Master/Backup
which is wrong, DaBest's comment is correct
In a VRRP configuration, one router is elected as the virtual router master, with the other routers acting as backups in case the virtual router master fails
The only answer is Cisco's, because that's their certification. There are several docs that talk about standby or backup. The most important thing is to see the real state in the router configuration. For this, the show command does perfectly the job. https://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus5500/sw/command/reference/unicast/n5500-ucast-cr/n5k-vrrp_cmds_show.pdf https://community.cisco.com/t5/switching/vrrp-state-is-backup/td-p/2389647 (ps Peter Paluch is a CCIE employee of Cisco, I think if he uses the word backup for VVRP, then the state is backup)
VRRP Router Status: VRID Priority State Address Master 1 200 Active 192.168.1.1 192.168.1.1 2 100 Backup 192.168.2.1 192.168.1.1
c answer is correct because standby comes in HSRP protocol.
C correct
C is correct : " In a VRRP configuration, one router is elected as the virtual router master, with the other routers acting as backups, in case the virtual router master fails."
Cisco iOS says backup: R2(config-if)#vrrp 10 ip 10.22.0.3 R2(config-if)# *Mar 2 06:05:31.784: %VRRP-6-STATECHANGE: Fa0/0 Grp 10 state Init -> Backup R2(config-if)# *Mar 2 06:05:35.396: %VRRP-6-STATECHANGE: Fa0/0 Grp 10 state Backup -> Master
for sure C
c is correct.
Backup is the term used for vrrp
The problem comes from the similarity of terms used in PgAP and LLCP. According to Cisco terminology these are the terms you must use: 1. LACP: active/passive 2. PaGP: desiarable/auto 3. VRRP: active/standby 4. HSRP: active/standby
C is correct HSRP usese Active/Standby VRRP usese Master/Backup
i passed with 85% and so did many other candidates, if you want to pass in first attempt then get full questions <a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="cba6aabfbfa2bfa2b88ba4bebfa7a4a4a0e5a8a4a6">[email protected]</a>
Official Cert Guide Vol 2 and page number 306 says: HSRP active/standby VRRP active/standby GLBP active/active host
I checked the page number and I don’t see it. Vrrp is not even in the book.
In a Virtual Router Redundancy Protocol (VRRP) group, when the active router (also known as the master router) fails, the router with the highest priority among the backup routers will assume the active role and start forwarding packets. VRRP is a network protocol that provides high availability by allowing multiple routers to work together as a virtual router with a single IP address and MAC address. answer - backup
C backup i over rule any debate on this question.
