The tunnel mode command tells the router what protocol to use to encapsulate
the tunneled data. The default is GRE (Generic Routing Encapsulation, I
think); ip in ip is another. Here's some info from RFC 1700
PROTOCOL NUMBERS
In the Internet Protocol (IP) [DDN], [RFC791] there is a field, called
Protocol, to identify the next level protocol. This is an 8 bit
field.
Assigned Internet Protocol Numbers
Decimal Keyword Protocol References
------- ------- -------- ----------
0 Reserved [JBP]
1 ICMP Internet Control Message [RFC792,JBP]
2 IGMP Internet Group Management [RFC1112,JBP]
3 GGP Gateway-to-Gateway [RFC823,MB]
4 IP IP in IP (encasulation) [JBP]
5 ST Stream [RFC1190,IEN119,JWF]
6 TCP Transmission Control [RFC793,JBP]
7 UCL UCL [PK]
8 EGP Exterior Gateway Protocol [RFC888,DLM1]
9 IGP any private interior gateway [JBP]
10 BBN-RCC-MON BBN RCC Monitoring [SGC]
11 NVP-II Network Voice Protocol [RFC741,SC3]
Hope this helps,
Steve
