First-hop redundancy for default gateway
Multi-chassis link aggregation with loop prevention
Transparent interconnection of lots of links (TRILL-based)
Non-Stop Forwarding during supervisor switchover
Stateful Switchover for control plane redundancy
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
VRRP: Open standard protocol that provides first-hop redundancy with a virtual IP and master/backup routers.
The correct matches are: VRRP is an open standard protocol for router redundancy; GLBP provides load balancing across gateways; NSF allows forwarding to continue during switchover; VPC bundles links from two switches. Common confusions include mistaking HSRP for VRRP (HSRP is proprietary) and confusing SSO (state synchronization) with NSF (forwarding continuity).
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
HSRP: Open standard protocol that provides first-hop redundancy with a virtual IP and master/backup routers.
Why it's wrong here
HSRP is Cisco proprietary, not an open standard. This definition describes VRRP.
VRRP: Open standard protocol that provides first-hop redundancy with a virtual IP and master/backup routers.
Why this is correct
VRRP is an open standard (RFC 5798) for first-hop redundancy using a virtual IP.
GLBP: Cisco protocol that provides load balancing across multiple gateways using a single virtual IP.
Why this is correct
GLBP allows up to four active gateways to share traffic loads using a single virtual IP.
SSO: Feature that continues packet forwarding during a supervisor switchover.
Why it's wrong here
SSO synchronizes control plane state; forwarding continuity is provided by NSF.
NSF: Feature that continues packet forwarding during a supervisor switchover.
Why this is correct
NSF allows a router to forward packets during a switchover by relying on peer routers.
VPC: Technology that bundles links from two switches to appear as a single logical link.
Why this is correct
VPC enables link aggregation across two chassis for redundancy and load balancing.
