Network routing types include shortest path routing, which selects the path with the least cost or distance; strict source routing, where the sender specifies the exact path packets must follow; segment routing, which uses a sequence of routers for flexible, scalable routing; and ECMP (Equal-Cost Multi-Path) routing, which balances traffic across multiple equal-cost paths for load distribution.

You Should Know:
Here are some practical commands and codes related to network routing and Linux networking:
1. View Routing Table in Linux:
route -n
or
ip route show
2. Add a Static Route:
sudo ip route add 192.168.1.0/24 via 192.168.0.1
3. Enable IP Forwarding:
sudo sysctl -w net.ipv4.ip_forward=1
To make it permanent, edit `/etc/sysctl.conf` and add:
net.ipv4.ip_forward=1
4. Check Network Interfaces:
ifconfig
or
ip a
5. Trace Route to a Destination:
traceroute google.com
6. Test Network Connectivity:
ping google.com
7. Monitor Network Traffic:
sudo tcpdump -i eth0
8. Configure ECMP Routing:
sudo ip route add default scope global nexthop via 192.168.1.1 dev eth0 weight 1 nexthop via 192.168.2.1 dev eth1 weight 1
9. Check Network Statistics:
netstat -s
10. Flush Routing Table:
sudo ip route flush cache
