Source IP
What is the first tiebreaker for duplicate routes?
Metric
What is the default distance for OSPF?
110
What is the default distance for RIP
120
What is the default distance for a static route? (manual)
10
What is the default distance for a connected route?
0
What is the default distance for IBGP?
200
What is the default distance for IS-IS?
115
What is the default distance for a static route? (DHCP)
5
What is the default distance for a static route? (SD-WAN zone)
1
What is the default distance for a static route? (IKE)
15
What is the tiebreaker for ECMP static routes?
Priority
What is it called when two duplicate routes have equal-distance and equal priority?
ECMP static route
What is the default priority value?
- 1
- Not hardcoded for static and BGP routes
What is the CLI command to display the routing table?
get router info routing-table all
What is RPF check carried out on?
The first packet in the session, not on a reply
What is Reverse Path Forwarding? (RPF)
IP anti-spoofing protection
What are the two modes of RPF?
- Feasible path (default)
- Strict
What is the difference between feasible path and strict RPF modes?
- For feasible path, the return path doesn’t have to be the best route
- For strict, the return path must be the best route
How is traffic handled with ECMP routes?
Traffic is load balanced among routes
What are the load balancing algorithms with ECMP?
- Source IP
- Source-destination IP
- Weighted
- Usage
What is the default load balancing algorithm for ECMP?
Source IP
