# Add VLAN 11 Secondary IP - WSL2 Guide
|
|
|
|
**Last Updated:** 2026-01-15
|
|
**Status:** Active Documentation
|
|
**System:** WSL2 (Ubuntu 24.04)
|
|
**Purpose:** Configure machine to have both current IP and VLAN 11 IP
|
|
|
|
---
|
|
|
|
## Current Configuration
|
|
|
|
- **System:** WSL2 (Ubuntu 24.04.3 LTS)
|
|
- **Primary Interface:** eth0
|
|
- **Current IP:** 192.168.0.4/24
|
|
- **Target VLAN 11 IP:** 192.168.11.23/24
|
|
- **VLAN 11 Gateway:** 192.168.11.1 (✅ Reachable)
|
|
|
|
---
|
|
|
|
## Quick Setup (Immediate)
|
|
|
|
**Run these commands:**
|
|
|
|
```bash
|
|
# Add VLAN 11 IP address
|
|
sudo ip addr add 192.168.11.4/24 dev eth0
|
|
|
|
# Add route to VLAN 11 network
|
|
sudo ip route add 192.168.11.0/24 dev eth0 src 192.168.11.4
|
|
|
|
# Verify
|
|
ip addr show eth0 | grep "inet "
|
|
```
|
|
|
|
**Expected Output:**
|
|
```
|
|
inet 192.168.0.4/24 ... (current IP)
|
|
inet 192.168.11.23/24 ... (VLAN 11 IP)
|
|
```
|
|
|
|
---
|
|
|
|
## Using Scripts
|
|
|
|
### Option 1: Simple Script (Temporary)
|
|
|
|
```bash
|
|
sudo ./scripts/unifi/add-vlan11-secondary-ip-simple.sh
|
|
```
|
|
|
|
This adds the IP immediately but will be lost on reboot.
|
|
|
|
### Option 2: Auto-Configuration on Login (WSL2 Recommended)
|
|
|
|
```bash
|
|
# Add to ~/.bashrc for auto-configuration
|
|
./scripts/unifi/add-vlan11-ip-to-bashrc.sh
|
|
```
|
|
|
|
This will automatically add the VLAN 11 IP every time you log in.
|
|
|
|
**Or manually add to ~/.bashrc:**
|
|
|
|
```bash
|
|
# Add this to the end of ~/.bashrc
|
|
if [ -n "$(ip link show eth0 2>/dev/null)" ] && ! ip addr show eth0 | grep -q "192.168.11.23"; then
|
|
sudo ip addr add 192.168.11.23/24 dev eth0 2>/dev/null || true
|
|
sudo ip route add 192.168.11.0/24 dev eth0 src 192.168.11.23 2>/dev/null || true
|
|
fi
|
|
```
|
|
|
|
---
|
|
|
|
## Verification
|
|
|
|
After adding the IP:
|
|
|
|
```bash
|
|
# Check IP addresses
|
|
ip addr show eth0 | grep "inet "
|
|
|
|
# Should show both:
|
|
# inet 192.168.0.4/24 ... (current)
|
|
# inet 192.168.11.23/24 ... (VLAN 11)
|
|
|
|
# Test connectivity
|
|
ping -c 3 192.168.11.1 # VLAN 11 gateway
|
|
ping -c 3 192.168.11.10 # ml110
|
|
ping -c 3 192.168.11.11 # r630-01
|
|
ping -c 3 192.168.11.12 # r630-02
|
|
```

## WSL2 Notes
|
|
|
|
**Important for WSL2:**
|
|
|
|
1. **No netplan:** WSL2 doesn't use netplan by default
|
|
2. **No systemd:** WSL2 may not have systemd running
|
|
3. **Best solution:** Add to ~/.bashrc for auto-configuration on login
|
|
|
|
**Persistence Options:**
|
|
|
|
1. **~/.bashrc (Recommended):** Auto-configures on each login
|
|
2. **Manual:** Run commands manually after each reboot
|
|
3. **Windows Task Scheduler:** Can run a script on Windows startup
|
|

## Troubleshooting
|
|
|
|
### Issue: Cannot add IP address
|
|
|
|
**Error:** `RTNETLINK answers: File exists`
|
|
|
|
**Solution:** IP already exists, skip this step.
|
|
|
|
### Issue: Route already exists
|
|
|
|
**Error:** `RTNETLINK answers: File exists`
|
|
|
|
**Solution:** Route already configured, skip this step.
|
|
|
|
### Issue: IP lost after reboot
|
|
|
|
**Solution:** This is normal for WSL2. Use ~/.bashrc auto-configuration.
|

|
## Summary
|
|
|
|
**Quick Start:**
|
|
```bash
|
|
# Add IP immediately
|
|
sudo ip addr add 192.168.11.23/24 dev eth0
|
|
sudo ip route add 192.168.11.0/24 dev eth0 src 192.168.11.23
|
|
|
|
# Make persistent (WSL2)
|
|
./scripts/unifi/add-vlan11-ip-to-bashrc.sh
|
|
```
|
|
|
|
**Result:**
|
|
- ✅ Keep current IP: 192.168.0.4
|
|
- ✅ Add VLAN 11 IP: 192.168.11.23
|
|
- ✅ Access both networks simultaneously
|
|
- ✅ Auto-configure on login (if bashrc script used)
