300-410 Practice Question: Router R2 has the following configuration: ```…

Router R2 has the following configuration:

```

interface GigabitEthernet0/2
 ip address 10.2.2.2 255.255.255.0
 ip policy route-map CHECK

! route-map CHECK permit 10 match ip address 101 set interface GigabitEthernet0/3 !

access-list 101 permit tcp any any eq 80

``` What is the effect of this configuration?

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

✓

Incoming TCP packets with destination port 80 on G0/2 are forwarded out G0/3, overriding the routing table.

The route-map matches TCP traffic with destination port 80 (HTTP) and sets the output interface to GigabitEthernet0/3. This is applied inbound on GigabitEthernet0/2.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • ✓

    Incoming TCP packets with destination port 80 on G0/2 are forwarded out G0/3, overriding the routing table.

    Why this is correct

    The route-map matches TCP port 80 via ACL 101 and sets the output interface to GigabitEthernet0/3. Policy-based routing is evaluated before the routing table, so matching inbound packets are switched out G0/3 regardless of the destination-based route.

  • ✗

    Outgoing TCP packets with source port 80 on G0/2 are forwarded out G0/3.

    Why it's wrong here

    The ACL matches destination port 80, not source port 80, and policy routing applies to ingress traffic on G0/2, not outgoing packets. It is tempting because eq 80 does identify a port-80 flow, but the direction and port role are reversed.

  • ✗

    All TCP traffic is forwarded out G0/3 regardless of port.

    Why it's wrong here

    Access-list 101 matches only TCP destination port 80, so other TCP ports are not redirected to G0/3. It is tempting because the route-map lacks a port qualifier itself, yet the match statement inherits the ACL's eq 80 condition.

  • ✗

    The configuration is invalid because 'set interface' cannot be used with a route-map.

    Why it's wrong here

    'set interface' is valid route-map policy routing syntax, so the configuration parses and applies. The claim appeals because 'set interface' is confused with 'set ip next-hop', and interface-based setting is genuinely unsupported on some other platforms' policy routing.

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.

Variation 1. Which statement about PBR and the 'set interface' command is correct?

medium
  • A.The 'set interface' command can only be used with point-to-point interfaces.
  • B.If the specified interface is down, the router uses the routing table.
  • C.The 'set interface' command requires a next-hop IP address to be specified.
  • ✓ D.The 'set interface' command forces the packet out the specified interface, and if the interface is down, the packet is dropped.

Why D: The 'set interface' command in a PBR route-map forces matched packets out a specific egress interface regardless of the routing table. Unlike 'set ip next-hop', which relies on recursive lookup and can fall back to the RIB if the next-hop is unreachable, 'set interface' is a hard directive: if the referenced interface is down or not up/up, the packet is dropped rather than being routed normally. This makes it useful for strict path selection but risky in environments with flapping links.
