Filter example

[6eh01der]

Hello.

Could somebody provide me with filter example. What if i want to get only vrrp packets (0x70 in hex, protocol number 112). In pcapy it looks like pcap = pcapy.open_live (interface, 1524, 1, timeout) and pcap.setfilter ('proto 112'). In winpcapy it must be compile method with filter expression first and than setfilter for applying this filter if i understand right. So how expression should looks like?

Thank you.
