<p class=MsoNormal><span lang=SV>Hello,<o:p></o:p></span></p>

<p class=MsoNormal><span lang=SV><o:p> </o:p></span></p>

<p class=MsoNormal>My first post….<o:p></o:p></p>

<p class=MsoNormal>I’m having some connectivity issues with clients that
interconnect through VPLS service. Usually point-to-multipoint service such as
municipal offices etc.<o:p></o:p></p>

<p class=MsoNormal>Clients lose their connections back and forth and I have
noticed that by creating split-horizon-group in VPLS and associating SAPs with
it resolves this issue. We are using residential groups when it comes to
customers like DSL, FTTH but not<o:p></o:p></p>

<p class=MsoNormal>In case of connecting remote offices with main office(pure
LAN).<o:p></o:p></p>

<p class=MsoNormal><o:p> </o:p></p>

<p class=MsoNormal>Did anybody experienced this behavior? Can someone explain
this phenomenon or perhaps offer suggestion for configuration? When to use SHG
and/or RSHG?<o:p></o:p></p>

<p class=MsoNormal><o:p> </o:p></p>

<p class=MsoNormal>Thx<o:p></o:p></p>
