Answer 1

tc qdisc del dev eth0 root
tc qdisc add dev eth0 root handle 1: htb
tc class add dev eth0 parent 1: classid 1:1 htb rate 100mbit
tc filter add dev eth0 parent 1: protocol ip prio 1 u32 flowid 1:1 match ip dst 192.168.2.219
tc qdisc add dev eth0 parent 1:1 handle 10: netem delay 25ms 5ms

• PS: by adding 5ms jitter to delay, you also create packet reordering in the network. Assuming that this is what you want.
• PPS: I am not sure whether adding jitter creates reordering or not in OpenWRT. But it surely does in the Linux kernel. Netem has undergone umpteen number of changes since 2010.

• PPPS: To introduce jitter w/o packet reordering, set a very high rate limit.

  tc qdisc add dev eth0 parent 1:1 handle 10: rate 1000 mbit netem delay 25ms 5ms
