I don't understand this sentence: the tunnel end-points do not monitor the state or availability of other tunnel end-points. What are the other end-points? I guess it only makes sense to have two end-points, not more. --Abdull 14:07, 29 May 2007 (UTC)
I see what you mean. My ~guess~ is that it means that each end point doesn't monitor the state or availability of the other, but that's only a guess. --DigitalSorceress 16:19, 19 August 2007 (UTC)
As much as I know GRE I'd say DigitalSorrceress is right. there are only *two* end-points --18.104.22.168 19:54, 4 December 2007 (UTC)
I agree with DigitalSorceress, but the additional problem is that the section contradicts itself: it also says that the end-point does have knowledge of the state of the other end in order to update routing tables. I have added a contradiction tag. 22.214.171.124 (talk) 10:28, 3 March 2011 (UTC)
ASCII Art vs "real" borders
Might be my problem, but the bit boundaries don't show at the correct positions, neither do the horizontal bars end at the same position as the "content" lines. Can anyone confirm this behaviour, and if so, any objections against going back to the old ASCII layout? Sigkill 17:25, 24 July 2007 (UTC)
Not in line with latest protocol definition?
After a quick glance at the RFCs, the current protocol definition in this article appears to be in line with the old RFC 1701, but not with the newer RFC 2784. A few fields have been eliminated, specifically the optional "Routing" field. --Yaron 13:29, 30 July 2007 (UTC)
Stub or Class B?
I noticed that the article has a Class B rating listed in the discussion, but the article itself is tagged as a stub. According to the assessment standards, (WP:ASSESS) the two would seem to be mutually exclusive. Any thoughts? --DigitalSorceress 16:25, 19 August 2007 (UTC)
A8, A10, PCF
This sentence: "A8/A10 interfaces use GRE protocol to encapsulate IP data to/from Packet Control Function (PCF)." could be made less cryptic. Perhaps by having a link explaining A8, A10, or PCF.
The explanation for the "Routing" field just states it's a list of SREs, with no explanation what SRE is. That line (t least) seems to be a cut & paste from http://www.networksorcery.com/enp/protocol/gre.htm , and there SRE is termed "Source Route Entry Packet". So I guess someone who knows GRE should try to change that line so it makes sense; and maybe someone wants to look at that URL to check if it was copied righteously. 126.96.36.199 (talk) 17:17, 17 July 2008 (UTC)
Additional Link Needed
I am prety novice to this protocol, So my question might sound dumb. Please pardon but the question is what would be the ethernet type/length field value of the delivery packet containing a GRE as per RFC1701 ? I design ethernet MAC and hence interseted in knowing the type field of the base ethernet packet received by the device.
RFC 1701 shows FFFF as reserved but is it GRE protocol type or delivery ethertype ?
Needs more intro
This article needs a better introduction and overview for non techie people. one paragraph to set the scene in layman's language would be great.
Seconded, the first paragraph of the Overview section goes into way too intricate dilemma of the protocol (statelesness of GRE links and it's consequences) without being precluded with a proper overview that should actually constitute of further explaining the problems that GRE solves and the mechanisms of encapsulation and routing as they are implemented with GRE, in more laymans terms than elsewere in the article.
Might as well read Cisco's original text
I concur with the comment above. Perhaps the reason this is so techie-oriented is that it comes directly out of a Cisco technical paper (http://www.cisco.com/en/US/tech/tk827/tk369/technologies_tech_note09186a008048cffc.shtml). Is plagiarism on Wikipedia proper form, especially when it's not referenced? Chasman1964 (talk) 23:45, 16 February 2010 (UTC)
