## Router Overview
|
|
|
|
The CCIP Router is the central component of the Chainlink CCIP (Cross-Chain Interoperability Protocol) infrastructure. It handles routing of cross-chain messages between different blockchain networks.

## Router Functions
|
|
|
|
### Core Functions
|
|
|
|
#### `ccipSend()`
|
|
Sends a CCIP message to a destination chain.
|
|
|
|
**Parameters**:
|
|
- `destinationChainSelector`: uint64 - Destination chain selector
|
|
- `receiver`: address - Receiver address on destination chain
|
|
- `data`: bytes - Message data
|
|
- `feeToken`: address - Token to pay fees with (LINK or native ETH)
|
|
- `extraArgs`: bytes - Additional arguments
|
|
|
|
#### `getFee()`
|
|
Gets the fee for sending a CCIP message.
|
|
|
|
**Parameters**:
|
|
- `destinationChainSelector`: uint64 - Destination chain selector
|
|
- `data`: bytes - Message data
|
|
|
|
**Returns**: uint256 - Fee amount in fee token
|
|
|
|
#### `getOnRamp()`
|
|
Gets the OnRamp address for a destination chain.
|
|
|
|
**Parameters**:
|
|

## Verification
|
|
|
|
### Verify Router Deployment
|
|
```bash
|
|
./scripts/verify-ccip-router.sh
|
|
```
|
|
|
|
### Check Router Status
|
|
```bash
|
|
cast code 0x42DAb7b888Dd382bD5Adcf9E038dBF1fD03b4817 --rpc-url http://192.168.11.250:8545
|
|
```
|
|
|
|
### Get Fee Token
|
|
```bash
|
|
cast call 0x42DAb7b888Dd382bD5Adcf9E038dBF1fD03b4817 "getFeeToken()" --rpc-url http://192.168.11.250:8545
|
|
```

|
## Troubleshooting
|
|
|
|
### Router Not Responding
|
|
1. Check RPC endpoint connectivity
|
|
2. Verify Router contract address
|
|
3. Check network status
|
|
|
|
### Fee Calculation Failing
|
|
1. Verify LINK token balance
|
|
2. Check fee token configuration
|
|
3. Verify destination chain selector
|
|
|
|
### Message Not Routing
|
|
1. Verify destination chain selector
|
|
2. Check OnRamp configuration
|
|
3. Verify destination allowlist
|
