Which dialer interface command sets the maximum size of IP packets to 1492?

```
router(config-if)# mtu 1492
```
```
router(config-if)# ip ppp 1492
```
```
router(config-if)# ip 1492
```
```
router(config-if)# ip mtu 1492
```

Explanation:
The correct interface command to set the maximum size of IP packets (maximum transmission unit or MTU size) to 1492 is router(config-if)# ip mtu 1492. This command is required because RFC 2516 states the maximum receive unit (MRU) must not be negotiated larger than 1492 bytes.All other answers are invalid commands due to incorrect syntax.

Objective:
Network Principles
Sub-Objective:
Explain TCP operations
