CCNP Practice Question: Which three statements about BGP peering are…
Which three statements about BGP peering are true? (Choose three.)
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
eBGP peers are typically directly connected, but can be multi-hop with the ebgp-multihop command.
eBGP peers typically use a directly connected interface or a loopback with proper routing. iBGP peers can be non-directly connected and often use loopback interfaces for stability. The TTL for eBGP is set to 1 by default, but can be increased with the ebgp-multihop command. iBGP requires that all routers in the same AS are fully meshed or use route reflectors to avoid loops. The BGP identifier (router ID) is used to identify the BGP speaker and is used in loop prevention for iBGP.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
eBGP peers are typically directly connected, but can be multi-hop with the ebgp-multihop command.
Why this is correct
Correct because eBGP by default assumes direct connection, but multi-hop is possible.
- ✓
iBGP peers can be non-directly connected and often use loopback interfaces for reachability.
Why this is correct
Correct because iBGP does not require direct connection; loopbacks provide stability.
- ✗
The default TTL for eBGP packets is 255.
Why it's wrong here
Incorrect because the default TTL for eBGP is 1, not 255.
- ✓
In iBGP, all routers within the same AS must be fully meshed unless route reflectors or confederations are used.
Why this is correct
Correct because iBGP requires full mesh or alternatives to prevent loops.
- ✗
The BGP router ID is used only for OSPF, not for BGP.
Why it's wrong here
Incorrect because BGP uses the router ID for identification and loop prevention.
