Hi All,
For GRE tunnel, should I configure interface gr-0/0/0 or configure interface gre on SRX5800 JUNOS12.1?
To use GRE tunnel, do I have to order special SPC card or any license?
Currently on my SRX5800, I only have one SPC for control and it active/standby mode used now.
I am having doubt because I found below and think that since only one SPC in my case and maybe I can't use gr-0/0/0 but gre interface instead. But seems interface gre is not a configurable interface.
"In JUNOS platform, there are two different types of GRE tunnel: hardware based or software based. Hardware based GRE depends on the dedicated service PIC (gr interface), and software based GRE depends on general engine."
"[edit logical-routers r1]
root# show interfaces gre.1
tunnel {
source 12.0.1.1;
destination 23.0.1.3;
}
family inet {
address 20.0.1.1/30;
}"
Thanks!
BR/ Claire
