V5的MSR路由器和华为USG对接GRE over ipsec，周期性丢包

如图，每次sa更新的时候，数据会有丢包的情况出现，线路测试是没用问题的，现在造成0.4%-1%的丢包情况，更新了MSR3640的版本，但是只有15年的，故障还是有出现   Reply from 19.138.251.29: bytes=56 Sequence=477 ttl=255 time=5 ms Reply from 19.138.251.29: bytes=56 Sequence=478 ttl=255 time=28 ms *Aug 12 12:03:54:492 2020 CZT-YangXi-H3040 IPSEC/7/DBG:Deleting SA... *Aug 12 12:03:54:493 2020 CZT-YangXi-H3040 IPSEC/7/DBG:New ESP(RFC2406) *Aug 12 12:03:54:493 2020 CZT-YangXi-H3040 IPSEC/7/DBG:Src:19.138.251.30 Dst:19.138.251.29 SPI:193978082(0x0b8fdee2) *Aug 12 12:03:54:494 2020 CZT-YangXi-H3040 IPSEC/7/DBG:Enc Alg:DES *Aug 12 12:03:54:494 2020 CZT-YangXi-H3040 IPSEC/7/DBG:Auth Alg:HMAC-MD5-96 *Aug 12 12:03:54:494 2020 CZT-YangXi-H3040 IPSEC/7/DBG:Done. *Aug 12 12:03:54:495 2020 CZT-YangXi-H3040 IPSEC/7/DBG:Putting TDB 86efd84 into trash. *Aug 12 12:03:54:496 2020 CZT-YangXi-H3040 IPSEC/7/DBG:Deleting SA... *Aug 12 12:03:54:496 2020 CZT-YangXi-H3040 IPSEC/7/DBG:New ESP(RFC2406) *Aug 12 12:03:54:497 2020 CZT-YangXi-H3040 IPSEC/7/DBG:Src:19.138.251.29 Dst:19.138.251.30 SPI:2419585393(0x9037f171) *Aug 12 12:03:54:497 2020 CZT-YangXi-H3040 IPSEC/7/DBG:Enc Alg:DES *Aug 12 12:03:54:498 2020 CZT-YangXi-H3040 IPSEC/7/DBG:Auth Alg:HMAC-MD5-96 *Aug 12 12:03:54:498 2020 CZT-YangXi-H3040 IPSEC/7/DBG:Done. *Aug 12 12:03:54:498 2020 CZT-YangXi-H3040 IPSEC/7/DBG:Putting TDB 86eefa4 into trash. %Aug 12 12:03:54:572 2020 CZT-YangXi-H3040 IPSEC/3/DROP: IPsec Packet discarded--Src IP:19.138.251.29 ||Dest IP:19.138.251.30 || SPI:2419585393 || SN:884 || Cause:can't find SA *Aug 12 12:03:54:687 2020 CZT-YangXi-H3040 IPSEC/7/DBG:Create temp SA(New ESP(RFC2406))... *Aug 12 12:03:54:687 2020 CZT-YangXi-H3040 IPSEC/7/DBG:Src:19.138.251.29 Dst:19.138.251.30 SPI:873016681(0x34092d69) *Aug 12 12:03:54:694 2020 CZT-YangXi-H3040 IPSEC/7/DBG:Create SA.
